Hundreds of men in pickups and on motorcycles allegedly shot and threw rocks at police and soldiers.
Hamdy Azzazy, a human rights activist, said, "The military attempted to withdraw to avoid bloodshed, but the armed men fired at them so they engaged, leaving the residents running for cover."
The assailants reportedly chanted slogans about Egypt returning to Sharia law. "The attackers are Islamic extremists and they are heavily armed with machine guns, hand grenades and rocked-propelled grenades," asserted General Saleh Al Masry, the head of security in North Sinai. "The armed men attacked two police stations, and many soldiers and police officers have been injured while defending themselves. Three of the attackers were killed in the operation so far."
0545 GMT: Egypt is still taking in yesterday's developments when a declared "Friday of Unity" turned into a show of strength by Islamist groups who dominated the rallies in Tahrir Square in Cairo and in other cities.
Other opposition groups accused the Islamists of breaking an agreement, putting up banners such as "Islamic law about the Constitution", setting up "sound systems blasting anti-secular, anti-leftist propaganda", preventing other speakers from taking the stage, and effectively pushing other protesters out of Tahrir.
The secularist blogger Arabawy writes that the Islamists left Tahrir about 7 p.m. and "the secular forces started reclaiming the square again. Marches started, with strong chants: 'Civil (State)! Civil (State)!', and other chants for social justice and retribution for the martyrs’ families."

0525 GMT: Last night, after a day of confusion, rumour, and mourning, the Libyan opposition said that its own militiamen had killed the military commander, General Abdel Fattah Younes.
Ali Tarhouni, Minister of Finance in the National Transitional Council, said Younes had been killed by members of the Obaida Ibn Jarrah Brigade, a militia allied to the insurgency. According to Tarhouni, the militia leader who had been sent to retrieve Younes from the front line had been arrested and had confessed that "his lieutenants" had carried out the murder.
It is still unclear why Younes was being called back to the opposition centre in Benghazi, Libya's second-largest city. It has been reported that Younes, the former Minister of Interior under Muammar Qaddafi, was being interrogated in connection with his family's ties to the regime.
