A delegation of Arab foreign ministers, including those of Egypt and Jordan, will visit Gaza "soon" in a show of support for Palestinians, Arab League chief Nabil al-Arabi said Wednesday.

The ministers will also assess reconstruction needs in the battered enclave after a nearly month-long war between Israel and Hamas, Arabi said.

Israel indicated Wednesday it was prepared to extend a 72-hour ceasefire with Hamas unconditionally in the Gaza Strip as Egyptian mediators accelerated efforts to broker a longer-term truce.

Guns fell silent in the tiny Palestinian enclave on Tuesday morning, allowing millions of people on both sides to breathe a sigh of relief after the deaths of 1,875 Palestinians and 67 on the Israeli side.

Foreign Minister Jebran Bassil urged on Wednesday the United States to take a legal action against crimes committed by terrorist organizations in the Iraqi city of Mosul and the northeastern border town of Arsal.

“The U.S. should take action against the crimes against humanity that are committed by takfiri organizations in Mosul and Arsal,” Bassil told U.S. Ambassador to Lebanon David Hale during a meeting at the Bustros Palace.

Save the Children placed full-page adverts in British newspapers on Wednesday listing the names of 373 Palestinian children killed in Israel's offensive on Gaza, as part of the charity's campaign for a permanent ceasefire.

Israeli police on Tuesday announced the arrest of a Palestinian man suspected of leading the group that kidnapped and murdered three Israeli teenagers in June.

The United States said Tuesday that it expects to participate in Cairo talks between Israelis and Palestinians aimed at securing a lasting ceasefire in Gaza.

The Gaza truce drawn up by Egypt shows Cairo has an "indispensable" role mediating conflicts between Israel and Hamas, despite strained ties with the Palestinian faction, analysts said Tuesday.

Israel withdrew all of its forces from Gaza on Tuesday after nearly a month-long deadly campaign, as a 72-hour ceasefire announced by Cairo went into effect.

Former Cuban leader Fidel Castro compared Israel's offensive in Gaza on Tuesday to a "disgusting form of fascism" that its ally, the United States, is unable to control.

"I think that a new and disgusting form of fascism is emerging with considerable force at this moment in human history," Castro wrote in a column in the newspaper Granma titled "Palestinian Holocaust in Gaza."

Palestinian Foreign Minister Riyad al-Malki on Tuesday said he was optimistic the latest ceasefire in Gaza will hold, even as Palestinians renewed efforts to haul Israelis before the International Criminal Court for war crimes.

A 72-hour truce took hold in the shattered enclave earlier on Tuesday after a Cairo-brokered deal was accepted by both Hamas and Israel, ending 29 days of heavy fighting which has claimed more than 1,800 lives.

Khayri Hasan al-Masri fled his home in Beit Hanun with his wife and three children nearly three weeks ago when Israel announced the launch of its July 17 ground offensive.

They left a tidy white house, with its grassy courtyard, a palm tree and a lemon tree.
