Egyptian President Mohammed Morsi will travel to Turkey on Sunday for discussions expected to focus on the conflict in Syria, state media reported.

Morsi's visit will be his first to Turkey since he became Egypt's first democratically elected civilian president in June.

Egyptian President Mohamed Morsi said Monday that he opposes any foreign military intervention in the Syria conflict but believes President Bashar Assad must go.

In an interview with PBS television's Charlie Rose ahead of the U.N. General Assembly meeting in New York, Morsi said the diplomatic quartet of Egypt, Iran, Saudi Arabia and Turkey could help end the 18-month-old conflict.

An Islamist militant group said it launched a deadly cross-border attack on Israel from Egypt's Sinai in protest at a U.S.-made film mocking Islam, SITE Intelligence Group reported on Sunday.

Ansar Bait al-Maqdis (Partisans of Jerusalem) termed the attack a "Disciplinary Invasion Against those who Dared Against the Beloved Prophet," the U.S.-based monitoring agency said, citing a statement posted on Islamist websites.

Israel will not accept alterations to its 1979 peace treaty with Egypt, Israeli Foreign Minister Avigdor Lieberman said on Sunday, as ties between the two countries continue to fray.

"There is not the slightest possibility that Israel will accept the modification of the peace treaty with Egypt," Lieberman told Israeli public radio. "We will not accept any modification of the Camp David accords."

Egypt's new Islamist president, Mohamed Morsi, urged the United States late Saturday to change its approach to the Arab world to be able to repair relations and revitalize an alliance with Egypt.

Morsi will travel to New York on Sunday to take part in a meeting of the U.N. General Assembly.

Egypt's Supreme Administrative Court on Saturday rejected an appeal by Islamists demanding the reinstatement of parliament, saying it was no longer legal, according to a judicial source.

"The parliament no longer exists legally since the June 14 ruling by the Supreme Constitutional Court (SCC)" deeming it unconstitutional and ordering its dissolution, the Supreme Administrative Court said.

Israel has transferred to Egypt the bodies of three militants who killed an Israeli soldier in a cross-border raid, before being killed themselves, an Israeli military source said Saturday.

"Last night we handed over to Egyptian authorities the bodies of the three terrorists killed yesterday," the source told Agence France Presse, without elaborating.

An Israeli soldier and three militants who infiltrated from Egypt's Sinai peninsula were killed in a clash along the border on Friday, the army said.

It said troops came under fire from gunmen who sneaked across the border, sparking a firefight which killed the three attackers.

Egypt on Thursday reopened the Serapeum of Saqqara, a vast underground necropolis south of Cairo dedicated to the bulls of Apis, after 11 years and complete renovation of the historic pharaonic site.

The Serapeum, whose origin dates back to around 1400 BC, was discovered in 1851 by French Egyptologist Auguste Mariette, founder of the first department of Egyptian antiquities.

President Bashar Assad has hit out at Saudi Arabia, Turkey and Qatar, accusing them of arming Syrian rebels but insisting they will not win, according to excerpts from an interview to appear in an Egyptian newspaper on Friday.

"They suddenly saw money in their hands after a long period of poverty and think they can buy history and play a regional role," Assad told al-Ahram al-Arabi, which put excerpts from the interview on its website on Thursday.
