A French rally against the deadly Israeli offensive in Gaza once again descended into chaos Sunday as protesters looted shops and riot police lobbed tear gas and rubber bullets into the crowds.

The demonstration in the northern Paris suburb of Sarcelles is the third to have deteriorated in the space of eight days in a country that counts the largest Muslim population in western Europe and a huge Jewish community.

Hizbullah Secretary-General Sayyed Hassan Nasrallah expressed solidarity on Monday with the Palestinian people, voicing support to Hamas.

In a phone call between Nasrallah and Hamas leader Khaled Meshaal, the Hizbullah chief stressed that the Lebanese resistance stands by the intifada of the Palestinians.

Israel's U.N. ambassador denied on Sunday that an Israeli soldier had been abducted by Hamas militants.

The U.N. Security Council late Sunday deplored the mounting death toll in Gaza and appealed for an immediate ceasefire at an emergency session held on the worst day of fighting.

Meeting for two hours of urgent talks in New York, the 15-member Council also called for respect of international humanitarian law, including the protection of civilians.

The number of Palestinians killed by Israeli fire in the latest round of Gaza violence rose to 476, medics said, after announcing the deaths of 38 people early Monday.

Emergency services spokesman for the Gaza Strip Ashraf al-Qudra said they had found the bodies of three children and a man in a demolished home east of Khan Yunis in southern Gaza.

United Nations Secretary-General Ban Ki-Moon urged Israel to "exercise maximum restraint" and spare the lives of civilians in its campaign in Gaza, where Sunday's Palestinian death toll passed 100.

He also condemned the "atrocious action" of Israel in Shejaiya, near Gaza city, where a blistering hour-long assault at dawn left 62 people dead and at least 250 people wounded.

President Barack Obama expressed concern over the loss of life in Gaza in a call to Israeli Prime Minister Benjamin Netanyahu Sunday, and said Secretary of State John Kerry will travel to Cairo to seek an end to the fighting.

Obama, who condemned attacks by Hamas on Israel, "also raised serious concern about the growing number of casualties, including increasing Palestinian civilian deaths in Gaza and the loss of Israeli soldiers," the White House said, adding that Kerry will travel "soon" to the Egyptian capital.

Around 3,000 people staged a peaceful pro-Palestinian demonstration in Amsterdam on Sunday, calling for an end to the bloody Israeli invasion of the Gaza Strip, an Agence France-Presse correspondent said. 

People of all ages -- Arab and European -- gathered on the Museumplein square, opposite the renowned Rijksmuseum, before marching through the city center, carrying signs including "Stop the war" and "Israel war criminals."

Egypt's foreign ministry on Sunday summoned Turkey's charge d'affaires over criticism of Cairo's handling of the war between Israel and Hamas in neighboring Gaza.

Turkey and Egypt withdrew their ambassadors last year after the military ousted Egyptian Islamist president Mohammed Morsi, who had forged closer ties with Turkey's devout premier, Recep Tayyip Erdogan.

Kuwait called on the international community Sunday to apply pressure on Israel to "stop its aggression" on Gaza following a visit by Hamas chief Khaled Meshaal to the Gulf state.

Kuwait, which holds the rotating presidency of both the Arab League and the Gulf Cooperation Council (GCC), also announced its backing for an Egyptian truce proposal which was turned down by Hamas.
