An Islamist coalition led by the Muslim Brotherhood on Saturday offered negotiations to end the deadly tumult since Egyptian President Mohammed Morsi's overthrow, without explicitly insisting on his reinstatement.

The coalition "calls on all revolutionary forces and political parties and patriotic figures to enter a deep dialogue on exiting the current crisis," it said in a statement.

Egypt unveiled Friday a multimillion dollar renovation project for Cairo's famed Egyptian Museum, including plans to demolish a scorched building that stands between it and the Nile, in a bid to draw tourists back and restore a sense of normalcy after more than two years of unrest.

Organizers said they want to return the dusty 111-year-old museum to its former glory by painting the walls and covering the floors in their original colors and patterns.

A teenager was killed Friday when supporters and opponents of Mohammed Morsi clashed in the Egyptian city of Alexandria, officials said, as backers of the ousted president rallied in and around Cairo.

The pro-Morsi demonstrations came just a day after the government lifted on Thursday a state of emergency and curfew that had been imposed in August after a deadly crackdown on Islamists in Cairo.

Russia is offering to sell Egypt modern helicopters and air defense systems in a landmark deal reportedly worth $2 billion that would mark a revival of large-scale military cooperation, a Russian official said Friday.

Russian Foreign Minister Sergei Lavrov and Defense Minister Sergei Shoigu visited Egypt on Thursday seeking lucrative contracts with the government after the ousting of Islamist president Mohammed Morsi.

Clashes in Cairo and its suburbs have killed at least 989 people since security forces launched an August 14 crackdown on supporters of ousted Egyptian president Mohammed Morsi, a forensic official told Agence France Presse Thursday.

On August 14 itself, 627 people were killed when security forces stormed Cairo's Rabaa al-Adawiya square to disperse a sit-in by Morsi's backers, said Hisham Abdul Hamid, spokesman for Egypt's forensic authorities.

The trial of the Muslim Brotherhood chief and his deputies on charges related to protest deaths will resume on December 11, judicial sources said Thursday, after the previous judges withdrew.

The three judges who had presided over the trial of Mohamed Badie and 34 co-defendants, including his two deputies, rescued themselves on October 29 for what they said were "reasons of conscience".

Egypt and Russia's defense ministers have discussed military collaboration between their countries, Russian Foreign Minister Sergei Lavrov said Thursday during a landmark visit to Cairo.

Lavrov and Defense Minister Sergei Shoigu led a high-level delegation on a visit that came in the wake of a diplomatic spat between Egypt and long-time ally the United States triggered by the ouster of Islamist president Mohammed Morsi.

An Egyptian court sentenced 12 supporters of deposed Islamist president Mohammed Morsi to 17 years in prison on Wednesday for taking part in a violent student-led protest, state media reported.

The official MENA news agency reported that the protesters were convicted of attacking the headquarters of the Islamic Al-Azhar institution during the protest.

Egypt claimed Wednesday it has not forced any Syrian refugees to leave the country as alleged by Human Rights Watch, adding that an entry visa requirement would soon be dropped.

"No Syrian refugee is made to depart from Egypt unless they have been proven to have entered the country through illegal immigration, an action contrary to Egyptian law," a government statement said.

A year after trading fire in a week-long war in Gaza, Israel and Hamas are squaring up for another confrontation, despite both sides appearing reluctant to make the first move.

More than 170 Palestinians and six Israelis were killed when hostilities erupted after an Israeli missile killed Hamas military chief Ahmed Jaabari last November 14.
