60 wounded in clashes between Egypt president's supporters and opposition protesters Violence breaks out in Cairo, Egypt, outside Mohammed Morsi's presidential palace. NBC's Jim Maceda has more on the clashes and a possible constitutional compromise by the Egyptian government. Updated at 4:25 p.m. ET -- Opposition protesters fought presidential supporters outside the Egyptian presidential palace on Wednesday, while inside the building the president's deputy proposed a way to end a crisis over a draft constitution that has split the most populous Arab nation. Stones and petrol bombs flew between opposition protesters and supporters of President Mohammed Morsi, and the Interior Ministry said 32 people had been arrested and three police vehicles destroyed. The Egyptian ministry of health told NBC News 60 people have been wounded in the clashes, but said there have been no fatalities. Riot police were deployed between the two sides to try to stop confrontations that flared after dark despite an attempt by Vice President Mahmoud Mekky to ease the crisis. Mekky said amendments to disputed articles in the draft constitution could be agreed on with the opposition. A written agreement could then be submitted to the next parliament, to be elected after a referendum on the constitution on Dec. 15. "There must be consensus," he told a news conference, saying opposition demands had to be respected to reach a solution. Ready for dialogue In a news conference Wednesday, opposition coordinator Mohamed ElBaradei said: "We hold President Morsi and his government completely responsible for the violence happening in Egypt today." "We are ready for dialogue if the constitutional decree is canceled ... and the referendum on this constitution is postponed," he said of the document written by an Islamist-led assembly that the opposition says ignores its concerns. Opposition leaders have previously urged Morsi to retract the Nov. 22 decree, defer the referendum and agree to revise the constitution, but have not echoed calls from street protesters for his overthrow and the "downfall of the regime." Morsi has said his decree was needed to prevent courts still full of judges appointed by ousted leader Hosni Mubarak from derailing a constitution vital for Egypt's political transition. Protests spread to other cities, and offices of the Muslim Brotherhood's political party in Ismailia and Suez were torched.
