GAZA CITY, Gaza Strip (AP) — Tens of thousands of displaced Palestinians returned to their Gaza neighborhoods Saturday, weaving through dust-shrouded streets as bulldozers clawed through the wreckage of two years of war and a ceasefire held in its second day.

“Gaza is completely destroyed. I have no idea where we should live or where to go,” said Mahmoud al-Shandoghli as he walked through Gaza City. A boy climbed a shattered building to raise the Palestinian flag.

About 200 U.S. troops arrived in Israel to monitor the ceasefire with Hamas. They will set up a center to facilitate the flow of humanitarian aid as well as logistical and security assistance. The head of the U.S. military’s Central Command said he visited Gaza on Saturday.

“This great effort will be achieved with no U.S. boots on the ground in Gaza,” Adm. Brad Cooper said in a statement.

An Egyptian official said U.S. envoy Steve Witkoff met with senior U.S. and Israeli military officials in Gaza and that Witkoff stressed the implementation of the ceasefire deal's first phase. The official spoke on condition of anonymity because he wasn’t authorized to talk to reporters.

Witkoff was expected to speak Saturday evening as thousands of Israelis gathered in Tel Aviv for a weekly rally that many hoped would be the last. Israel’s military has said the 48 hostages still in Gaza would be freed Monday. The government believes around 20 remain alive.

Aid groups urged Israel to reopen more crossings to allow aid into Gaza. A U.N. official, speaking on condition of anonymity to discuss details not yet public, said Israel has approved expanded aid deliveries, starting Sunday.

The World Food Program said it was ready to restore 145 food distribution points across the famine-stricken territory, once Israel allows for expanded deliveries. Before Israel sealed off Gaza in March, U.N. agencies provided food at 400 distribution points.

Though the timeline and how the food will enter Gaza remain unclear, the distribution points will allow Palestinians to access food at more locations than they could through the U.S.- and Israel-backed Gaza Humanitarian Foundation, which had operated four locations since taking over distribution in late May.

COGAT, the Israeli military body in charge of humanitarian aid, said more than 500 trucks entered Gaza on Friday, although many crossings remain closed. Some 170,000 metric tons of food aid have been positioned in neighboring countries awaiting Israeli permission.

Israelis waited anxiously for the return of the remaining hostages, who were among some 250 taken in Hamas’ Oct. 7, 2023, attack on Israel that sparked the war.

“It’s been a few nights that we can’t sleep. We want them back and we feel that everything is just hanging on a thread,” Maayan Eliasi, a Tel Aviv resident, said at the city's Hostages Square.

Israel is to free some 250 Palestinians serving prison sentences, as well as around 1,700 people seized from Gaza the past two years and held without charge. The Israel Prison Service said prisoners have been transferred to deportation facilities at Ofer and Ktzi’ot prisons, “awaiting instructions from the political echelon.”

Questions remain on who will govern Gaza after Israeli troops gradually pull back and whether Hamas will disarm, as called for in the ceasefire agreement.

Prime Minister Benjamin Netanyahu, who unilaterally ended the previous ceasefire in March, has suggested Israel could resume its offensive if Hamas fails to disarm.

“If it’s achieved the easy way, so be it. If not, it will be achieved the hard way,” Netanyahu said Friday, pledging that the next stage would bring Hamas’ disarmament.

The scale of Gaza's destruction will become clearer if the truce holds. More than three out of every four buildings have been destroyed, the U.N. said in September — a volume of debris equivalent to 25 Eiffel Towers, much of it likely toxic.

The death toll is expected to rise as more bodies are found that couldn't be retrieved during Israel's offensive.

A manager at northern Gaza’s Shifa Hospital told The Associated Press that 45 bodies pulled from the rubble in Gaza City had arrived over the past 24 hours. The manager, speaking on condition of anonymity for safety reasons, said the bodies had been missing for several days to two weeks.

U.S. President Donald Trump’s initial 20-point plan calls for Israel to maintain an open-ended military presence inside Gaza, along its border with Israel. An international force, largely of troops from Arab and Muslim countries, would be responsible for security inside Gaza, though the timeline is unclear.

Egyptian President Abdel-Fattah el-Sissi on Saturday called for the Gaza deployment of an international force authorized by the U.N. Security Council.

The Israeli military has said it will continue to operate defensively from the roughly 50% of Gaza it still controls after pulling back to agreed-upon lines.

Witkoff told Israeli officials on Friday that the United States would establish a center in Israel to coordinate issues concerning Gaza until there is a permanent government, according to a readout of the meeting obtained by the AP. Another official who was not authorized to speak to the media confirmed the readout's contents.

The readout said no U.S. soldiers will be on the ground in Gaza, but there will be people who report to the U.S. and aircraft might monitor over the strip.

The Hamas-led 2023 attack on southern Israel killed some 1,200 people.

In Israel’s ensuing offensive, more than 67,000 Palestinians have been killed in Gaza, according to Gaza’s Health Ministry, which doesn’t differentiate between civilians and combatants but says around half the deaths were women and children. The ministry is part of the Hamas-run government, and the U.N. and many independent experts consider its figures to be the most reliable estimate of wartime casualties.

The war has also triggered other conflicts in the region, sparked worldwide protests and led to allegations of genocide that Israel denies.
