Egypt's army said Sunday it has destroyed 13 more tunnels connecting the Sinai Peninsula to the Gaza Strip, taking to 1,639 the overall number it has laid waste to.

Israel on Saturday approved a four-hour extension of a temporary truce in Gaza, Israeli television said, after the Palestinian death toll topped 1,000 with the retrieval of more than 130 bodies.

Channel 10 said the security cabinet had agreed to prolong a 12-hour truce that went into effect on Saturday morning by four hours, extending it until midnight local time (2100 GMT).

Not a stone is left standing at the Najjar family home in southern Gaza. Yesterday it was a three-story building, today medics dug 22 bodies of out the crater where it once stood.

The scene was one repeated across the Gaza Strip on Saturday, as desperate residents ventured out during a fragile 12-hour truce only to be met with evidence of death and destruction on a scale that reduced men to tears.

Turkey on Saturday allowed the resumption of flights to Tel Aviv's Ben Gurion airport after Israel and Hamas agreed to a temporary ceasefire in Gaza, the state civil aviation authority said on Saturday.

"Taking into account the current ceasefire, the flight ban on Israel's Ben Gurion Airport has been lifted, pending a subsequent announcement," Turkish Ministry of Transport's Directorate General of Civil Aviation (SHGM) said on Twitter.

An Israeli colonel likens the hunt for tunnels dug by Palestinian militants from the coastal enclave of Gaza to the work of a detective.

"Finding these tunnels is like a detective trying to solve a murder with a number of clues. There are several pieces to the puzzle, including intelligence and technology," said Lieutenant Colonel Max of the army engineers for the Gaza area.

U.S. Secretary of State John Kerry and top diplomats from Europe and the Middle East gathered in Paris Saturday called for an extension to a temporary truce currently in force between Israel and Hamas.

Both sides have agreed to a 12-hour "humanitarian" ceasefire in Gaza that started at 0500 GMT Saturday, putting a brief stop to a conflict that has killed more than 1,000 Palestinians -- a large majority of them civilians.

A parliament session was held on Saturday in order to express Lebanon's solidarity with the Palestinian Gaza Strip and the Iraqi city of Mosul.

The session was chaired by Speaker Nabih Berri and attended by the majority of political blocs.

U.S. Secretary of State John Kerry said Friday no ceasefire deal had been reached yet in the conflict in Gaza as he and U.N. chief Ban Ki-moon urged a seven-day halt in fighting, which has killed 848 Palestinians in 18 days.

Kerry, who has been leading international efforts to reach a truce, said at a press conference in Cairo with Ban that both sides "still have some terminology" to agree to on a ceasefire, but added they had "fundamental framework" on a truce.

About 1,000 pro-Palestinian demonstrators marched through Berlin Friday, closely watched by police for any banned anti-Semitic slogans and separated from pro-Israel rallies.

More than 1,000 officers were on guard in the rainy capital for the rally against Israel's Gaza offensive that has killed more than 845 people, most of them Palestinian civilians.

Turkey's foreign minister on Friday met Hamas chief Khaled Meshaal in the Qatari capital Doha to help efforts to broker a ceasefire with Israel, a government official said.

Ahmet Davutoglu met Meshaal in Doha for "negotiations aimed at a fair ceasefire," the official told Agence France-Presse on condition of anonymity. "The talks are proceeding in a positive direction."
