Egypt protesters breach barriers, march on palace Updated at 2:23 p.m. CAIRO Tens of thousands of Egyptian protesters pushed past barbed wire fences installed by the army and marched on the presidential palace Friday, calling for President Mohammed Morsi to "leave" a day after they say he offered no concessions to opposition demands. Climbing over tanks of the Republican Guard, protesters streamed toward the palace as night fell Friday, crossing a no-go zone set up around the compound's perimeter. The area witnessed deadly clashes on Wednesday, when supporters of Morsi's Muslim Brotherhood group drove out crowds camped outside the palace. The clashes left at least six dead and hundreds injured, deepening the schism between the two sides. Egypt is plunging deeper into crisis as protesters - mainly liberals - press Morsi to call off a referendum on a draft constitution agreed by his allies. Rival protests also took place in cities around the country, including in the cities of Alexandria on the Mediterranean coast and Luxor in the south. CBS News correspondent Holly Williams says Egyptian television reported fresh clashes Friday between supporters and opponents of Morsi in front of a mosque in Alexandria, but there were no reports of injuries or serious violence. Also Friday, the head of Egypt's election committee said the planned voting on the referendum of Egyptians who live abroad had been postponed. The announcement could signal an attempt by Morsi to give a room for negotiations with the opposition, which is demanding the cancelation of the whole referendum set for a nationwide vote on Dec. 15. Ismail Hamdi said that the weeklong expatriate voting, which had been due to begin Saturday, will begin Wednesday instead. The two camps in the country's divide appeared at a deadlock, after Morsi gave a fiery televised speech Thursday night denouncing his opponents and refusing to call off the referendum, even as he appealed for dialogue. The opposition rejected talks, saying he must first cancel the referendum and meet other demands. With Egypt's crisis now in its third week, anger was mounting in the streets. Each side is depicting the conflict as an all-out fight for Egypt's future and identity. The opposition accuses Morsi and his Islamist allies of turning increasingly dictatorial to force their agenda on the country, monopolize power and turn Egypt to a religious state. The Muslim Brotherhood, from which Morsi hails, and other Islamists say the opposition is trying to use the streets to overturn their victories in elections over the past year and stifle popular demands to implement Islamic shariah law. The tone was one of a battle cry as thousands of Islamists held funeral prayers Friday at Al-Azhar Mosque - the country's premier Islamic institution - for Morsi supporters killed in Wednesday's clashes. Seeking to rally their side, a series of speakers to the crowd portrayed the opposition as tools of the regime of ousted leader Hosni Mubarak - or as decadent and un-Islamic - and vowed to defend a constitution they say brings Islamic law to Egypt. "Egypt is Islamic, it will not be secular, it will not be liberal," the crowd chanted in a funeral procession filling streets around the mosque. During the funeral, thousands chanted, "With blood and soul, we redeem Islam," pumping their fists in the air. Mourners yelled that opposition leaders were "murderers." One hardline cleric speaking to the crowd denounced anti-Morsi protesters as "traitors." Another declared that they will not allow Egypt to become "a den of hash smokers." "We march on this path in sacrifice for the nation and our martyrs," a leading Brotherhood figure, Mohammed el-Beltagy, told the crowd. We will keep going even if we all become martyrs. We will avenge them or die like them. Bread! Freedom! Islamic Law!" the crowd chanted, twisting the revolutionary slogan of "Bread! Social Justice!" used by leftists and secular activists in the 2011 uprising against Mubarak. At presidential palace in an upscale neighborhood, many protesters were furious over the president's speech the night before in which he accused "hired thugs" of attacking protesters outside the palace Wednesday, sparking the clashes. Most witnesses say the clashes began with Morsi supporters attacked a tent camp set up by anti-Morsi protesters. A series of video clips surfaced the days following the bloody Wednesday, showing badly bruised faces of female activists, a man putting his hand over the mouth of prominent female activist Shahanda Mekalad to try to silence her as she chanted "we are the Egyptian people," and other anti-Morsi protesters stripped naked and beaten up by the Morsi supporters. One protester was pictured with a bloodstained shirt and a bruised face. Wednesday's battles have only fed into mistrust between Islamists in power and liberal opposition. Republican Guards intervened on Thursday for the first time, posting tanks around the palace and stringing barbed wire. Morsi attended weekly Friday prayers at the Republican Guards' mosque near the palace - after he was denounced by worshippers last week at a mosque near his home in a Cairo suburb where he often prays. Morsi has been hit by a string of resignations by some of his top aides protesting the week's violence. Criticism is also growing from Egyptian journalists, including those working for state-run news organizations, over what they say are attempts by Islamists to control the media. Ultraconservative Islamists known as Salafis rallied Friday in front of Egypt's Media City south of Cairo to protest media coverage by privately owned networks they say is being used as a propaganda machine against the faithful. Led by lawyer-turned-cleric Hazem Salah Abu-Ismail, with his trademark long, gray beard, the Salafis raised black flags and signs reading "hypocritical media," and brought bedspreads for a prolonged sit-in. Anti-riot police were deployed to the area. The National Salvation Front, the main opposition umbrella group, blasted Morsi's speech, saying he was "surprisingly in denial to facts that millions of people in Egypt and around the world have seen" - that the violence Wednesday came from "clear and blatant instigation by leaders of the Muslim Brotherhood, from which the president hails."
