Egyptian President Mohamed Morsi has postponed an official visit to France this week, the French presidency said Tuesday, as days of deadly clashes brought his rule to the brink of collapse.

Morsi had been due to meet French President Francois Hollande on Friday to discuss France's military intervention in Mali, which he has criticized.

The Syrian opposition on Tuesday told French senators that it wanted arms but no foreign intervention in Syria, a Senate committee said after a hearing.

"The delegation said it was disappointed by the global community's lack of support and stressed the need for it to receive weapons to wage an effective fight, which isn't currently possible," the foreign affairs and defense committee said in a statement.

Israel's foreign ministry on Tuesday protested to Argentina's ambassador over his country's agreement with Iran to create an independent commission to investigate the deadly 1994 attack on a Jewish center in Buenos Aires, a spokesman said.

"The ambassador of Argentina in Israel was summoned today to the Ministry of Foreign Affairs in Jerusalem for a clarification talk," ministry spokesman Yigal Palmor said in a statement.

British Prime Minister David Cameron will head to Algeria on Wednesday for a two-day visit in the wake of the hostage crisis that left some 37 foreigners dead including several Britons, his office confirmed.

Cameron is expected to meet with his Algerian counterpart Abdelmalek Sellal as well as President Abdelaziz Bouteflika, Downing Street said Tuesday.

U.S. President Barack Obama on Tuesday announced an extra $155 million dollars to aid refugees fleeing what he said was "barbarism" propagated by the Assad government against Syrians.

Obama, unveiling a grant, which will take U.S. humanitarian help to Syrians to $365 million, also promised that the Assad regime "will come to an end. The Syrian people will have their chance to forge their own future."

Israel's parliamentary vote did not end hopes for peace with the Palestinians but instead has opened up a new chance for dialogue, U.S. Secretary of State Hillary Clinton argued Tuesday.

"I actually think this election opens doors, not nails them shut," she said, during a so-called "global townhall" meeting, in which she took questions from Internet-users and broadcasters around the world.

After winning a tug-of-war with the opposition over Egypt's new constitution in December, Islamist President Mohamed Morsi faces a fresh crisis, one that is hard to pass without him making concessions.

The gravity of the crisis was highlighted Tuesday by Defense Minister General Abdel Fattah al-Sissi, who warned if the current situation persists it could "lead to a collapse of the state".

Iraqi officials said Tuesday they would up the salaries of Sunni militiamen who fought al-Qaida during the country's brutal sectarian war, the latest bid to appease mostly-Sunni anti-government rallies.

The immediate two-thirds increase in wages for the Sahwa, otherwise known as the Sons of Iraq or the Awakening, comes as officials have trumpeted a substantial prisoner release in the face of more than a month of demonstrations in the country's north and west.

Israel on Tuesday boycotted a special U.N. Human Rights Council review of its rights situation, becoming the first country ever to snub such a session.

"I see that the delegation of Israel is not in the room," council president Remigiusz Henczel told the delegates at the United Nations in Geneva.

Palestinian fighter Saeed Marragha, alias Abou Moussa, died of illness Tuesday in Syria where his Fatah-Intifada group was based decades after splitting from the mainstream Fatah faction, his group said.

Abou Moussa "died at dawn at a hospital" in Damascus, succumbing to a long illness, a Fatah-Intifada spokesman said, adding the veteran military commander would be buried in Syria's capital following noon Muslim prayers on Wednesday.
