CAIRO -- Egypt postponed early voting on a contentious draft constitution, and aides to President Mohammed Morsi floated the possibility of canceling the whole referendum in the first signs Friday that the Islamic leader is finally yielding to days of protests and deadly street clashes.
Tens of thousands marched on the presidential palace after pushing past barbed wire fences installed by the army and calling for Mr. Morsi to step down. Thousands also camped out in Tahrir Square, birthplace of the uprising that toppled Hosni Mubarak in 2011.
A spokesman for Mr. Morsi's Muslim Brotherhood urged the group's supporters to practice "self-restraint" after hundreds gathered in front of a mosque near the presidential palace. He appealed for them not to march to the palace and to avoid confrontation.
The announcement by the election committee head Ismail Hamdi to delay early voting on the charter came as a surprise, and it was difficult to predict whether it will lead to a breakthrough in the political crisis.
The president's aides said the move would ease some pressure and would provide room for negotiations with the opposition.
But Mr. Morsi's opponents have rejected talks, saying he must first cancel the referendum and meet other demands. Late Friday, an opposition umbrella group called for an open-ended sit-in in front of the presidential palace.
The crisis began Nov. 22, when Mr. Morsi issued a decree that gave him absolute powers and immunity from judicial oversight. It deepened when he called for a Dec. 15 national referendum on the draft constitution hurriedly produced by the Islamist-led constituent assembly. The draft was infused with articles that liberals fear would pave the way for Islamizing Egypt.
Legal Affairs Minister Mohammed Mahsoub said the administration was weighing several proposals -- including calling off the referendum and returning it to the constituent assembly for changes. Another possibility was disbanding the constituent assembly and forming a new one, either by direct vote or an agreement among the political forces.
"We have a big chance tomorrow," Mr. Mahsoub told the Qatari-based Al-Jazeera network, referring to what he said was a meeting between Mr. Morsi and political forces. "There are no deadlines or referendums outside the country. Tomorrow or day after, we might reach a good agreement."
Vice President Mahmoud Mekki also told the broadcaster that he had contacted leading democracy advocate Mohamed ElBaradei to join Mr. Morsi in a dialogue. Mr. ElBaradei leads the newly formed National Salvation Front, a group of liberals and youths who opposed Mr. Morsi's decrees and led the protests in Cairo.
In a televised speech, Mr. ElBaradei made clear the opposition's demands: cancellation of the declaration that Mr. Morsi used to give himself immunity from judicial oversight and postponement of the referendum.
"The people are angry because they feel their rights have been raped," Mr. ElBaradei said on the ONTV network. "If he takes these decisions, he will be opening the door for dialogue. I hope he is listening."
The opposition National Salvation Front rejected talks with Mr. Morsi, urging an ongoing sit-in at the palace and warned of assaults on the protesters and more violence.
"We reject the fake dialogue which Morsi has called for. No talks after bloodshed and before holding those responsible accountable," the front said in a statement.
Some protesters expressed optimism after they heard that the early voting for Egyptians abroad, which was due to begin Saturday, had been put off until Dec. 5.
"This looks like the beginning of a retraction," said Mohsen Ibrahim, a 56-year-old demonstrator. "This means Morsi may postpone the referendum. It looks like the pressure is working out."
But he warned that "if Morsi doesn't see the numbers of people protesting, then he will be repeating the same mistake of Mubarak."
Since the Arab Spring uprising that toppled Mubarak, Egypt has been split between Islamists and mostly secular and liberal protesters. Each side depicts the conflict as an all-out fight for Egypt's future and identity.
The opposition accuses Mr. 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 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 at Al-Azhar Mosque -- the country's premier Islamic institution -- for Morsi supporters killed in Wednesday's clashes. A series of speakers portrayed the opposition as tools of the Mubarak regime, or as decadent and un-Islamic.
"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. Mourners yelled that opposition leaders were "murderers."
One hard-line cleric denounced anti-Morsi protesters as "traitors." Another said Egypt would not be allowed 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! Freedom! Social justice!" used against Mubarak.
At the same time, the anti-Morsi demonstrators streamed in from different parts of Cairo to the presidential palace in an upscale neighborhood for a fourth straight day.
Many were furious over the president's speech Thursday night in which he accused "hired thugs" of attacking protesters. Most witnesses said Wednesday's clashes began with supporters of the president attacking a tent camp set up by the anti-Morsi crowd.
Pressure on Mr. Morsi also came from his inner circle after he was hit by a string of resignations by some top aides protesting the violence. Criticism is also growing from journalists, including those working for state-run news organizations, over what they say are attempts by Islamists to control the media. Judges are on strike for two weeks and said they are not going to oversee the vote as stipulated by law, something that would erode the credibility of the process.world
