Major floods sweep northeast Australia

SYDNEY: Two people were missing and the body of a third person was recovered from raging floodwaters as severe storms pounded northeastern Australia on Sunday, forcing more than 1,000 to flee their homes.

Army aircraft were deployed in the northern state of Queensland, where storms generated by former tropical cyclone Oswald unleashed punishing rains and localised tornadoes and floodwaters threatened several major towns.

One woman was plucked to safety in Biloela, 600 kilometres northwest of the state capital Brisbane, after she spent eight hours clinging to a tree.

At Gympie, north of Brisbane, three families waited on the roofs of their homes for seven hours before rescue helicopters, hampered by high winds, managed to reach them, town mayor Ron Dyne said.

A 27-year-old man was missing after he tried to cross a swollen creek near Gympie, and state Premier Campbell Newman said there were serious concerns for another young woman.

"Emergency services are searching for a young woman who reportedly drove into waters near Pacific Haven this morning, and we have grave fears for her safety," Newman told reporters.

Separately on Sunday, police said the body of an elderly man who went to check on a yacht had been recovered from waters north of Bundaberg, where the engorged Burnett River broke its banks and was expected to engulf 300 homes.

Bundaberg was among dozens of towns devastated by floods in Queensland two years ago that claimed 35 lives. Newman said residents there were bracing for the river to peak above nine metres, well in excess of the 7.92 metres seen in 2011.

Further north at Gladstone, about 900 homes were evacuated and several towns in the region were already isolated by the rising waters.

Across the state some 58,000 homes were without power and that number was growing by the hour, according to Newman.

"We are right in the middle of this now, I can hear it bucketing down on the roof as we speak," he said.

Authorities warned residents in New South Wales to prepare for possible flash floods and strong winds of up to 100 kilometres per hour on Monday as the storm system moves further south, the AAP news agency reported.

Prime Minister Julia Gillard said the emergency had revived "memories of the floods of two summers ago", which she said were "still fresh".

The Insurance Council of Australia declared a statewide catastrophe, noting that there had already been "severe inundation... in several towns and cities" and that major flood warnings had been issued.

"Unfortunately, this catastrophe declaration is the result of the first cyclone to come close to the coast this season, and the weather bureau has warned it's highly possible we will see more before the end of summer," said council chief Rob Whelan.

At least one international flight was diverted from Brisbane to Sydney due to the high winds and Qantas cancelled a number of domestic services, with the Sunshine Coast regional airport shut down.

A staggering 1-1.5 metres of rain was estimated to have fallen since the storms began.

Cyclones and floods are common in Australia's northeast during the warmer summer months. A massive inundation of Queensland in 2011 killed 35 people and brought Brisbane to a standstill for several days, swamping some 30,000 homes.

Brisbane was expected to be spared the kind of flooding seen two years ago, with officials predicting 3,600 homes and 1,250 businesses will be inundated, none in the central city.

Oppo BDP-105: Not your average Blu-ray player

The Oppo BDP-105 Blu-ray, SACD, and DVD-Audio player

Even by Oppo's high standards the BDP-105 is an extraordinary Blu-ray player. Sure, it's loaded with up-to-the-second features -- 4K upscaling, 2D-to-3D conversion, and a high-quality USB 2.0 digital-to-analog converter -- but what really makes the Oppo special is the sound. Pop the cover and look inside and you'll see why. Most of the 17-pound component's chassis space is devoted to the audio circuitry. That's nice, but the audio advantages will be completely irrelevant if you connect the BDP-105 to your receiver with a HDMI cable (the digital-to-analog conversion would then be handled in the receiver). The 105 was designed for buyers still using older $1,000 or $2,000 receivers from the days before HDMI connectivity, that would like to hear the Blu-rays' high-resolution DTS Master Audio or Dolby TrueHD soundtracks at their best. Since the audio won't be transmitted over the HDMI cable, you would run audio cables between the 105's seven- or five-channel analog outputs and the AV receiver's analog inputs.

Or you could forgo the receiver entirely and hook up the BDP-105 directly to a five- or seven-channel power amplifier. That approach would produce better sound quality, but would lack the connectivity, flexibility, and convenience of today's better receivers. Still, the BDP-105/power amp combo would sound better and be more powerful than most top-of-the-line receivers. The 105's connectivity options won't match any decent receiver, but its connectivity suite is a lot more extensive than most Blu-ray players. The Oppo has two HDMI inputs, so you can connect external devices such as set-top boxes and network streaming devices, three USB 2.0 ports, coaxial and optical digital inputs for satellite boxes, televisions, video-game consoles, etc., and there's a built-in headphone amplifier. The BDP-105's extensive bass management options are on par with a lot of AV receivers. The player's digital volume control is easy to use.

For my listening tests, I hooked up the BDP-105 ($1,199) with an assortment of self-powered Audioengine and Emotiva monitor speakers, and a Hsu subwoofer. With this setup I didn't need to use an AV receiver or separate power amp, but the Raconteurs' "Live at Montreux" Blu-ray was vivid and very live sounding. The system's freewheeling dynamics were really impressive, and the surround mix on King Crimson's "Red" DVD-A projected a remarkably seamless wrap-around soundstage. Each instrument was precisely focused in a near 360-degree sound environment.

The BDP-105 has full speaker setup and bass management options, just like an AV receiver.

Classical music on SACD was just as impressive, the front three speakers produced a three-dimensional soundstage with lots of depth, and string tone was top notch. Dramatic movies on Blu-ray and DVD sounded great. I plugged headphones into the BDP-105, but the sound wasn't special, Schiit Audio's $99 Magni headphone amp was a lot better.

The $499 Oppo BDP-103 shares most of the BDP-105's features, but lacks the upgraded digital-to-analog converters, so if you're planning on using HDMI to connect the player to your receiver, buy the 103, and save $700. You can use the 103's 7.1 analog outputs with an old high-end receiver lacking HDMI connectivity, but the 103's digital converters are a step down from the ones in the 105.

The BDP-105 is an update of the Oppo BDP-95, and the new one has lots of features the old player lacks, but the two players sound about the same. Oppo still has 95s in stock and sells them for $799.

Oppo sells direct and offers a 30-day money-back guarantee, and the return shipping is free.

Hackers take over gov't website

Last Updated 12:47 p.m. ET

WASHINGTON The hacker-activist group Anonymous says it hijacked the website of the U.S. Sentencing Commission to avenge the death of Aaron Swartz, an Internet activist who committed suicide.

The website of the commission, an independent agency of the judicial branch, was taken over early Saturday and replaced with a message warning that when Swartz killed himself two weeks ago "a line was crossed."

The message read in part:

Citizens of the world,
Anonymous has observed for some time now the trajectory of justice in the United States with growing concern. We have marked the departure of this system from the noble ideals in which it was born and enshrined. We have seen the erosion of due process, the dilution of constitutional rights, the usurpation of the rightful authority of courts by the "discretion" or prosecutors. We have seen how the law is wielded less and less to uphold justice, and more and more to exercise control, authority and power in the interests of oppression or personal gain."

The hackers say they've infiltrated several government computer systems and copied secret information that they now threaten to make public.

Family and friends of Swartz, who helped create Reddit and RSS, say he killed himself after he was hounded by federal prosecutors.

Officials say he helped post millions of court documents for free online and that he illegally downloaded millions of academic articles from an online clearinghouse.

By mid-morning Saturday the website was offline.

The FBI's Richard McFeely, executive assistant director of the Criminal, Cyber, Response, and Services Branch, said in a statement that "we were aware as soon as it happened and are handling it as a criminal investigation. We are always concerned when someone illegally accesses another person's or government agency's network."

Cops Using More Private Cameras to Nab Suspects

Philadelphia detectives were able to quickly make an arrest in the murder and burning of a female pediatrician by viewing surveillance video of nearby stores and a hospital that captured the suspect entering the doctor's home and later getting into his truck.

In the hours after Dr. Melissa Ketunuti's body was found strangled and burning in her basement, city's Homicide Task Force collected surveillance footage from a coffee shop, drug store and hospital overlooking Ketunuti's block. It was footage taken from Ori Feibush's coffee shop that allowed cops to identify Smith.

The suspect, an exterminator named Jason Smith, soon confessed to detectives, police said.

Lately a range of crimes have been solved by the seemingly ubiquitous security videos maintained by private companies or citizens, and investigators have been able to quickly apprehend suspects by obtaining the video, deftly turning private cameras into effective police resources.

Philadelphia Police Arrest Suspect in Doctor's Killing Watch Video

Pa. Doctor Killing: Person of Interest in Custody Watch Video

Private surveillance cameras have become so pervasive that the face of a suspect who allegedly shot a Bronx, N.Y., cab driver in a botched robbery on Jan. 14 was splashed throughout the media within days because the cabbie had rigged his vehicle with a camera.

The New York Police Department arrested Salvatore Perrone after he was caught on surveillance video recorded near two of three shopkeeper slayings in Brooklyn, N.Y., in November. He has since been charged with murder.

And in Mesa, Ariz., surveillance footage taken in November by resident Mitch Drum showed a man rolling on the ground trying to extinguish flames that had engulfed his shirt, which had caught fire while he was allegedly siphoning gas from a car by Drum's house. The man was arrested.

Though surveillance cameras have been a staple of security since a network of government operated cameras dubbed the "ring of steel" was introduced in London in the early 1990s, police have recently launched programs to partner with more businesses.

In Philadelphia, police have launched a program for businesses to register private cameras with the department. According to the SafeCam website, businesses will only be contacted when there is a criminal incident in the vicinity of the security camera. At that point, police will request a copy of the footage for their investigation.

"Businesses are saying, 'I have a camera at this location, and it may or may not be of use to you. It's a registration to say, 'feel free to call me,'" Sgt. Joseph Green told ABCNews.com

At least 26 die in Egyptian clashes over death sentences

PORT SAID, Egypt/CAIRO (Reuters) - At least 26 people died on Saturday when Egyptians rampaged in protest at the sentencing of 21 people to death over a soccer stadium disaster, adding to bloody street turmoil confronting Islamist President Mohamed Mursi.

Armored vehicles and military police fanned through the streets of Port Said after the violence. The state news agency quoted a general as saying the military aimed to "establish calm and stability in Port Said and to protect public institutions".

Unrest flared with nationwide rallies on Friday to mark the second anniversary of the overthrow of autocrat Hosni Mubarak, a democratic revolution that protesters now accuse Mursi of betraying by ramming through an Islamist-hued constitution.

While anniversary-related violence subsided, a new outbreak hit Port Said after a court sentenced 21 men to die for involvement in the deaths of 74 people after a local soccer match on February 1, 2012, many of them fans of the visiting team.

Residents ran wildly through the streets of Port Said, outraged that men from their city had been blamed for the stadium disaster, and gunshots were reported near the prison where most of the defendants were being held.

Security sources said 26 people, at least two of them policemen, had been killed in the Mediterranean coastal city. State television reported more than 200 people had been wounded.

Witnesses said some men stormed two police stations in Port Said, where protesters lit tires in the street, sending black smoke funneling into the air.

At least nine people were killed in clashes with police on Friday, mainly in the port of Suez where the army has also deployed. Hundreds were injured as police rained down tear gas on protesters armed with stones and some with petrol bombs.

The schism between Islamists and secular Egyptians is hurting efforts by Mursi, freely elected in June, to revive an economy in crisis - deprived of fresh investment and tourism due to political upheaval - and stem a slide in Egypt's currency.

The political strife and lack of security that has blighted the Arab world's most populous country over much of the post-Mubarak era is casting an ominous shadow over a parliamentary election expected to start in April.

DIVERSITY

Highlighting tensions, the opposition National Salvation Front coalition called for a government of national unity and an early presidential vote among other demands. It said it would call for more protests next Friday and could boycott the parliamentary election if its demands are not met.

Mursi's opponents say he has failed to deliver on economic pledges or be a president representing the full political and communal diversity of Egyptians, as he pledged.

His supporters say his critics do not respect the democracy that has given Egypt its first freely elected leader.

The Muslim Brotherhood, which propelled Mursi to office, said in a statement that "corrupt people" and media who were biased against the president had stirred up anger on the street and incited violence.

At the Port Said soccer stadium a year ago, many spectators were crushed and witnesses saw some thrown off balconies after the match between Cairo's Al Ahly and local team al-Masri.

Families of victims in court cheered and wept for joy when Judge Sobhy Abdel Maguid read a list of 21 names "referred to the Mufti", a phrase used to denote execution, as all death sentences must be reviewed by Egypt's top religious authority.

A total of 73 people have been standing trial. Other rulings will be issued on March 9, the judge said.

One relative in the court shouted: "God is greatest." Outside the Al Ahly club in Cairo, fans also cheered. They had threatened more violence unless the death penalty was meted out.

Thousands took to the streets of Cairo, Alexandria and other cities on Friday to protest against what they call the creeping authoritarianism of Mursi's rule. Protesters in Cairo were again hurling stones at police lines in Cairo on Saturday.

SEEKING CHANGE

"We want to change the president and the government. We are tired of this regime. Nothing has changed," said Mahmoud Suleiman, 22, in Cairo's Tahrir Square, the cauldron of the 2011 anti-Mubarak revolt and near where youths stoned police.

Ahmed Salama, 28, a protester camped out with dozens of others in Tahrir, said: "The protests will continue until we realize all the demands of the revolution - bread, freedom and social justice."

Ismailia and Suez, cities which like Port Said lie on the Suez Canal, witnessed some of the worst violence on Friday. But a canal official said the unrest on Friday and Saturday had not disrupted traffic in the waterway vital to international trade.

In a statement in response to Friday's violence, Mursi said the state would not hesitate in "pursuing the criminals and delivering them to justice". He urged Egyptians to respect the principles of the revolution by expressing views peacefully.

The president met on Saturday with the National Defence Council, which includes senior ministers and security officials, to discuss the spate of violence.

In a televised statement, the National Salvation Front said it was holding Mursi responsible for the disturbances.

The Front was formed from disparate groups last year when Mursi awarded himself extra powers and fast-tracked an Islamist-flavored constitution to a referendum, opposed by the Front although the document was passed in the popular vote.

"Egypt will not regain its balance except by a political solution that is transparent and credible, by a government of national salvation to restore order and heal the economy and with a constitution for all Egyptians," prominent opposition politician Mohamed ElBaradei wrote on his Twitter account.

Until the Front was formed, the opposition had struggled to unite and their vote had been split at presidential and parliamentary polls, helping Islamists. The last parliament was dissolved based on court order, demanding a new vote this year.

Mustapha Kamal Al-Sayyid, a professor of political science at Cairo University, said the latest violence reflected the frustration of many liberal-minded Egyptians and others.

"The state of polarization between Islamists and others is most likely to continue and will have a very negative impact on the state's politics, security and economy," he said.

Inspired by the popular uprising in Tunisia, Egypt's revolution spurred further revolts across the Arab world. But the sense of common purpose among Egyptians two years ago has unraveled, triggering bloody street battles last month.

10 police killed in Afghanistan suicide attack: official

KABUL: At least 10 policemen were killed and 18 others, mostly civilians, were wounded in a suicide attack Saturday in a crowded area of the northeast Afghan city of Kunduz, provincial authorities said.

The attacker, who was on foot, detonated his explosives next to a group of police officers, according to several sources.

"We have 10 dead, including the counter terrorism police chief and head of traffic police and their bodyguards," Sayed Sarwar Hussani, Kunduz police spokesman told AFP.

Thirteen civilians and five policemen were wounded in the blast, Hussani said, adding that the final death toll may rise.

The attack was "the work of the enemies of Afghanistan", he said, using a phrase common among Afghan officials to describe Taliban insurgents.

AFP could not immediately reach the Taliban for comment on the attack, which has so far not been claimed by any group.

Afghanistan's interior ministry and the provincial governor spokesman Enayatullah Khaleeq confirmed the toll.

According to the head of the Kunduz health department, Saad Mukhtar, 19 people in total were wounded in the attack, which police officials said took place around 5:20 pm, 12:50 GMT.

Such attacks have in the past been blamed on Taliban insurgents who are leading an 11-year insurgency against the US-backed government of President Hamid Karzai.

Taliban militants have stepped up their fight against Afghan troops as the country's forces are increasingly taking over security responsibility from US-led NATO troops.

Earlier Saturday, a suicide attacker on a bicycle killed two civilians in southeastern Afghanistan's Ghazni province, and on Friday a suicide bomber in a car attacked a NATO convoy in Afghanistan's strategic Kapisa province, killing at least five civilians and wounding 15 others.

Also this week a squad of Taliban suicide bombers attacked Kabul traffic police headquarters in the heart of the city, killing three police officers and wounding dozens others.

The attacks come at a crucial juncture for Afghanistan as US-led NATO troops are preparing for their withdrawal from the country by the end of 2014. Afghan and international observers have predicted a civil war could grip the country once foreign troops have pulled out.

Samsung unveils rugged Galaxy phone for the outdoor type

Galaxy Xcover 2

Samsung)

Samsung has created a new smartphone that can handle the great outdoors and even spend time underwater.

Announced today, the Galaxy Xcover 2 is built as a durable and rugged device, according to Samsung. The phone is both dustproof and sandproof.

It can also hold its breath underwater, at least at a depth of around three feet for up to thirty minutes. No, you probably won't be making too many phone calls under the water. But the Xcover 2's camera can come in handy if you want to snap photos of life under the sea.

The phone provides Google map information and an enhanced GPS/GLONASS feature. Combing both the U.S.-based GPS and Russia's GLONASS can track your location more accurately, according to Samsung.

The camera's LED flash is bright enough so it can be used like a torch in dark conditions. The 1,700mAh battery boasts a capacity of 570 hours. To get in shape, the phone includes a Cardio Trainer Pro app so you can set up and monitor a personalizing training program.

Outfitted with
Android 4.1 Jelly Bean, the Xcover 2 is powered by a 1GHz dual-core processor. The 4-inch screen offers a WVGA display.

A 5-megapixel autofocus camera is found in the back, while a VGA camera faces front. The phone is equipped with Bluetooth version 4.0, which Samsung says can detect other Bluetooth devices more than 164 feet away.

Samsung has not yet announced where or when the phone will be available, nor how much it will cost. But the timing is just right for the company to show off the Xcover 2 and reveal more details at next month's Mobile World Congress in Barcelona.

Court: Obama appointments are unconstitutional

President Barack Obama violated the Constitution when he bypassed the Senate to fill vacancies on a labor relations panel, a federal appeals court panel ruled Friday.

A three-judge panel of the U.S. Court of Appeals for the D.C. Circuit said that Obama did not have the power to make three recess appointments last year to the National Labor Relations Board.

The unanimous decision is an embarrassing setback for the president, who made the appointments after Senate Republicans spent months blocking his choices for an agency they contended was biased in favor of unions.

The ruling also throws into question Obama's recess appointment of Richard Cordray to head the Consumer Financial Protection Bureau. Cordray's appointment, also made under the recess circumstance, has been challenged in a separate case.

Obama claims he acted properly in the case of the NLRB appointments because the Senate was away for the holidays on a 20-day recess. But the three-judge panel ruled that the Senate technically stayed in session when it was gaveled in and out every few days for so-called "pro forma" sessions.

GOP lawmakers used the tactic - as Democrats have in the past as well - to specifically to prevent the president from using his recess power. GOP lawmakers contend the labor board has been too pro-union in its decisions. They had also vigorously opposed the nomination of Cordray.

The Obama administration is expected to appeal the decision to the U.S. Supreme Court, but if it stands, it means hundreds of decisions issued by the board over more than a year are invalid. It also would leave the five-member labor board with just one validly appointed member, effectively shutting it down. The board is allowed to issue decisions only when it has at least three sitting members.

On Jan. 4, 2012, Obama appointed Deputy Labor Secretary Sharon Block, union lawyer Richard Griffin and NLRB counsel Terence Flynn to fill vacancies on the NLRB, giving it a full contingent for the first time in more than a year. Block and Griffin are Democrats, while Flynn is a Republican. Flynn stepped down from the board last year.

Obama also appointed Cordray on the same day.

The court's decision is a victory for Republicans and business groups that have been attacking the labor board for issuing a series of decisions and rules that make it easier for the nation's labor unions to organize new members.

Mars Rover Celebrates Milestone on Red Planet

It was never supposed to last this long. When the Mars rover Opportunity settled on the Martian surface nine years ago today, mission managers at NASA said they would be pleased if it lasted for 90 days.

Instead, it's been 3,201 days, and still counting. The rover has driven 22.03 miles, mostly at a snail's pace, from one crater to another, stopping for months at a time in the frigid Martian winters. The six motorized wheels, rated to turn 2.5 million times, have lasted 70 million, and are all still working.

"Opportunity is still in very good health, especially considering what it's gone through," said John Callas, manager of NASA's Mars Exploration Rover project. The surface of Mars is a pretty tough place; there can be temperature fluctuations of a hundred degrees each day. That's pretty hard on the hardware."

Video: '7 Minutes of Terror: A Landing on Mars

When Opportunity and its twin rover, Spirit, reached Mars in January 2004, there was a fair bit of sniping that NASA, with all that 90-day talk, was playing down expectations. It escalated when Steve Squyres of Cornell University, the principal investigator for the missions, said things like, "We're on Sol 300 of a 90-Sol mission." (A Sol is a day on Mars, and lasts 24 hours, 39 minutes.) Callas and others have insisted that the prediction was based on engineering, not a nod to public relations.

"There was an expectation that airfall dust would accumulate on the rover, so that its solar panels would be able to gather less electricity," said Callas. "We saw that on Pathfinder," a small rover that landed on Mars in 1997." The cold climate was also expected to be hard on the rovers' batteries, and changes in temperature from night to day would probably pop a circuit or two.

Instead, the temperatures weren't quite as tough as engineers had expected, and the rovers proved tougher. They did become filthy as the red Martian dust settled on them, reducing the sunlight on the solar panels -- but every now and then a healthy gust came along, surprising everyone on Earth by cleaning the ships off.

Spirit, in hilly territory on the other side of the planet, finally got stuck in crusty soil in 2009, and its radio went silent the next year. But Opportunity, though it's had some close calls, is -- well, you remember those commercials about the Energizer bunny.

So what do you do with an aging rover on a faraway planet? You keep using it. In its first weeks, NASA said Opportunity found chemical proof that there had once been standing water on the surface of Mars -- good news if you're looking for signs that the planet could once have been friendly to life. Since then, it's been sent to other places, with rocks and soil that are probably older, and with clay that may have been left by ancient rivers.

About 20 NASA staff members still work full-time on Opportunity at the Jet Propulsion Laboratory in Pasadena, Calif. Another 60 split their time between Opportunity and other projects, such as the Curiosity rover that landed last August. About 100 scientists, doing research on Mars, pop in and out.

In a few months, Callas said, Opportunity will head to an area nicknamed Cape Tribulation. The clay there could be rich in the minerals suggestive of past life.

They haven't done much to mark the ninth anniversary or the 3,200th Martian day, just a get-together earlier this week during a previously scheduled science conference. After that, Callas said, it was back to work.

"It's like keeping your car going," he said, "without ever having a chance to change the oil."

Violence flares on anniversary of Egypt uprising

CAIRO/ALEXANDRIA, Egypt (Reuters) - Protesters clashed with police across Egypt on Friday on the second anniversary of the revolt that toppled Hosni Mubarak, taking to the streets against the elected Islamist president who they accuse of betraying the revolution.

At least 91 civilians and 42 security personnel were hurt in violence across the country, officials said. Street battles erupted in Cairo, Alexandria, Suez and Port Said, where the Muslim Brotherhood's political party offices were torched.

Thousands of opponents of President Mohamed Mursi and his Muslim Brotherhood allies massed in Cairo's Tahrir Square - the cradle of the uprising against Mubarak - to revive the demands of a revolution they say has been hijacked by the Islamists.

The January 25 anniversary showcased the divide between the Islamists and their secular foes that is hindering Mursi's efforts to revive an economy in crisis and reverse a plunge in Egypt's currency by enticing back investors and tourists.

Inspired by Tunisia's ground-breaking popular uprising, Egypt's revolution spurred further revolts across the Arab world. But the sense of common purpose that united Egyptians two years ago has given way to internal strife that has only worsened and last month triggered lethal street battles.

"It's definitely tense on the ground, but so far there hasn't been anything out of the ordinary or anything that really threatens to fundamentally alter the political situation," said Shadi Hamid, director of research at the Brookings Doha Center.

The Brotherhood decided against mobilizing for the anniversary, wary of the scope for more conflict after violence in December that was stoked by Mursi's decision to fast-track an Islamist-tinged constitution rejected by his opponents.

The Brotherhood fiercely denies accusations of trampling on democracy as part of a smear campaign by its rivals.

Before dawn on Friday, police battled protesters who threw petrol bombs and firecrackers as they tried to approach a wall blocking access to government buildings near Tahrir Square.

Clouds of tear gas filled the air. At one point, riot police used one of the incendiaries thrown at them to set ablaze at least two tents erected by the youths, a Reuters witness said.

Skirmishes between stone-throwing youths and the police continued in streets around the square into the day. Ambulances ferried away a steady stream of casualties.

"Our revolution is continuing. We reject the domination of any party over this state. We say no to the Brotherhood state," Hamdeen Sabahy, a popular leftist leader, told Reuters.

There were similar scenes in Suez and Alexandria, where protesters and riot police clashed near local government offices. Black smoke billowed from tyres set ablaze by youths.

Police also fired tear gas to disperse dozens of protesters who tried to scale barbed-wire barriers protecting the presidential palace in Cairo, witnesses said. Other protesters broke into offices of provincial governors in Ismailia, east of Cairo, and Kafr el-Sheikh in the Nile Delta.

In Tahrir Square, protesters echoed the chants of 2011's historic 18-day uprising. "The people want to bring down the regime," they chanted. "Leave! Leave! Leave!" chanted others as they marched towards the square.

"We are not here to celebrate but to force those in power to submit to the will of the people. Egypt now must never be like Egypt during Mubarak's rule," said Mohamed Fahmy, an activist.

BADIE CALLS FOR "PRACTICAL, SERIOUS COMPETITION"

With its eye firmly on forthcoming parliamentary elections, the Brotherhood marked the anniversary with a charity drive across the nation. It plans to deliver medical aid to one million people and distribute affordable basic foodstuffs.

Writing in Al-Ahram, Egypt's flagship state-run daily, Brotherhood leader Mohamed Badie said the country was in need of "practical, serious competition" to reform the corrupt state left by the Mubarak era.

"The differences of opinion and vision that Egypt is passing through is a characteristic at the core of transitions from dictatorship to democracy, and clearly expresses the variety of Egyptian culture," he wrote.

Still, Mursi faces discontent on multiple fronts.

His opponents say he and his group are seeking to dominate the post-Mubarak order. They accuse him of showing some of the autocratic impulses of the deposed leader by, for example, driving through the new constitution last month.

"I am taking part in today's marches to reject the warped constitution, the 'Brotherhoodisation' of the state, the attack on the rule of law, and the disregard of the president and his government for the demands for social justice," Amr Hamzawy, a prominent liberal politician, wrote on his Twitter feed.

The Brotherhood dismisses many of the criticisms as unfair fabrications of their rivals, accusing them of failing to respect the rules of the new democracy that put the Islamists in the driving seat via free elections.

Six months into office, Mursi is also being held responsible for an economic crisis caused by two years of turmoil. The Egyptian pound has sunk to record lows against the dollar.

SOURCES OF FRICTION ABOUND

Other sources of friction abound. Little has been done to reform brutal Mubarak-era security agencies. A spate of transport disasters on roads and railways neglected for years is feeding discontent as well. Activists are impatient for justice for the victims of violence over the last two years.

These include hardcore soccer fans, or ultras, who have been rallying in recent days to press for justice for 74 people killed in a soccer stadium disaster a year ago in Port Said after a match between local side al-Masry and Cairo's Al Ahly.

The parties that called for Friday's protests listed demands including a complete overhaul of the constitution.

Critics say the constitution, which was approved in a referendum, offers inadequate protection for human rights, grants the president too many privileges and fails to curb the power of a military establishment supreme in the Mubarak era.

Mursi's supporters say that enacting the constitution quickly was crucial to restoring stability desperately needed for economic recovery, and that the opposition is making the situation worse by perpetuating unrest.
