Egyptian protesters clash with riot police near Cairo's Tahrir Square on January 28, 2013. Violence gripped Egypt for a fifth straight day on Monday as Egypt's main opposition bloc turned down an invitation to hold talks with President Mohamed Morsi and called instead for fresh mass protests.
A man was killed as police and protesters clashed in Cairo and lobbed rocks at each other on a bridge in an underpass leading to the capital's iconic Tahrir Square as tear gas hung heavily in the air.
The clashes continued sporadically throughout the day, witnesses said, accusing gunmen of opening fire on the demonstrators from rooftops.
"There are many people wounded by gunfire," Ahmad Doma, an activist at the scene, told AFP in the evening. He blamed the shootings on Muslim Brotherhood-linked militiamen.
A security source said two offices and nine soldiers were also injured in clashes around Tahrir Square, and that protesters torched two personnel carriers.
As the unrest showed no signs of abating, Egypt's Islamist-dominated Senate ratified a law that would grant the armed forces powers of arrest, a day after Morsi announced a crackdown.
Morsi, who hails from the Muslim Brotherhood, on Sunday declared a month-long state of emergency in Port Said, Suez and Ismailiya provinces where around 50 people were killed and hundreds wounded over the weekend.
He also slapped night-time curfews on the three provinces after attacks on police stations following death sentences passed on Saturday against 21 supporters of a Port Said football club over stadium violence last year that killed 74 people.
On Monday, hundreds of mourners marched in Port Said on a second day of funerals for those killed in the canal city.
And hundreds more took to the streets of the Mediterranean city of Alexandria, carrying Egyptian flags and chanting slogans against the Brotherhood, the official MENA news agency reported.
Although most of the bloodshed has focused on Port Said, the violence erupted on Thursday in Cairo on the eve of the second anniversary of the uprising that overthrew Hosni Mubarak, with police and protesters clashing.
Disgruntled Egyptians say the revolution failed to reach its goals of social justice.
Grappling with a deep economic crisis, the Arab world's most populous nation is also struggling to strike a balance between a leadership boasting the legitimacy of the ballot box and opponents who accuse it of betraying the revolution's goals.
-- Nationwide protests called for Friday --
-------------------------------------------
The National Salvation Front, a coalition of mainly liberal and leftist movements, called for countrywide protests on Friday.
"We will not participate in dialogue that is empty of content," leading dissident Mohamed ElBaradei told reporters after a meeting of the NSF.
The bloc wants the formation of a national salvation government and the amendment of the Islamist-drafted constitution, before it agrees to any talks.
An NSF statement called "on the Egyptian people to take to the streets in all Tahrir Squares (across the nation) on Friday to stress the sanctity of the blood of the martyrs and achieve the goals of the revolution."
The unrest also highlights a deep split between Morsi's mainly Islamist allies, and an opposition of leftists, liberals, Christians and Muslims calling for freedoms and the separation of the state from religion.
It likewise underscores long-standing tensions between protesters and a police force long accused of human rights abuses.
The new Senate-ratified law will see the armed forces "support the police in maintaining order and protecting vital installations until the end of parliamentary elections and whenever the National Defence Council (headed by Morsi) requests it."
The army will also "be given powers of arrest according to the law," the text says.
At least 46 people have died in the Suez Canal cities in three days, while hundreds have also been injured. Port Said was the worst hit with 40 fatalities, MENA reported on Monday as three of the injured died of their wounds.
The White House on Monday condemned the unrest and urged Egyptian leaders to make clear violence is never acceptable.
"We strongly condemn the recent violence that has taken place in various Egyptian cities. We look to all Egyptians to express themselves peacefully and look to Egyptian leaders to make clear that violence is not acceptable," it said.
Amnesty International also denounced "the unnecessary use of lethal force by security forces" and said it had collected "disturbing eyewitness accounts of excessive force."
Morsi has warned that he was ready to take further measures unless there was an end to the violence.
