Cairo/Gaza: Israeli forces pulled back from parts of Gaza City overnight, after a fierce, week-long offensive that met with Hamas resistance, leaving dozens of dead and wrecked homes and roads in the Palestinian enclave's biggest urban area, rescuers said.

The offensive, 10 months into Israel's campaign to eliminate Hamas militants, took place as US-backed mediators sought to finalise a peace deal that would free remaining hostages taken by the militants in their cross-border rampage on October 7, 2023.

The Gaza Civil Emergency Service said teams had collected around 60 bodies of Palestinians killed by Israeli forces over the past week from the area of Tel Al-Hawa and the edges of the Sabra neighbourhood in Gaza City.

While tanks withdrew from some areas, Israeli snipers and tanks continued to control some high ground, residents and rescue teams said, warning residents against trying to return.

"There are bodies scattered in the streets, dismembered bodies, there are bodies of entire families, there are also bodies inside a home of an entire family that was completely burned," Gaza Strip Civil Defense spokesperson Mahmoud Basal said on Friday in comments carried by media in Hamas-run Gaza.

Israel's military said it had found drones and other weaponry in what is called a Hamas combat complex inside the former UNRWA headquarters in Gaza City and had evacuated civilians from the area before attacking.

"The troops engaged in close-quarters combat with terrorist cells that had fortified themselves inside the UNRWA compound," it said, adding that it had also found an important Hamas tunnel nearby and weapons production under a university building.

The armed wings of Hamas and Islamic Jihad said they had attacked Israeli forces with anti-tank rockets and mortar fire, killing and wounding many. There has been no Israeli army comment on those claims.

Home to more than a quarter of Gaza's residents before the war, Gaza City was largely razed to the ground in late 2023, but hundreds of thousands of Palestinians had returned to homes in the ruins before Israel once again ordered them out.

Dozens of residents returned again on Friday to check the damage after civil emergency teams put out fires in the early hours. Reuters footage showed wrecked roads and buildings, including the former UNWRA headquarters. Bodies wrapped in white shrouds and bearing the names of the dead women and men lay on the floor at Al-Ahli Hospital.    

Aid worjkers killed
Musa Al-Dahdouh recalled heavy aerial and tank fire and said Israeli forces had detained and interrogated his two sons and their wives and children before allowing them to leave. "My mother is in a wheelchair, my wife as well, as she has metal in her arms and legs. My grandson is paralysed in the legs, his father had to carry him on his back," he said.

In Khan Younis in the southern Gaza, Hamas media said four people working for the Al-Khair Foundation, a Muslim NGO based in Britain and Turkey, were killed in an air strike at an aid distribution centre.

Arab mediators, backed by the United States, are trying to reach a ceasefire deal that would free Israelis held hostage by Hamas in return for many Palestinians jailed by Israel.

On Friday, a senior Hamas official blamed Israel for a failure to build on momentum created when the Islamist faction dropped a key demand in the US-drafted ceasefire offer a week ago to clear the way for a deal.

"Israel hasn't given a clear stance over Hamas proposal," said the official, who asked not to be named, accusing Israel of "stalling and wasting time." There was no immediate comment from Israel.

Israeli Prime Minister Benjamin Netanyahu said on Thursday he remained committed to the Gaza ceasefire framework and accused Hamas of making demands that contradicted it, without saying what those demands were.

Hamas-led militants killed 1,200 people and took more than 250 hostages on October 7, according to Israeli tallies. Since then, Israel's forces have killed more than 38,000 Palestinians, medical authorities in Gaza say.
