Israeli forces battled Hamas militants and bombed more targets in the devastated Gaza Strip Tuesday with the UN General Assembly due to vote on a new demand for a ceasefire.
More than two months into the war sparked by Hamas's October 7 attack, the visiting chief of the UN agency for Palestinian refugees, Philippe Lazzarini, likened Gaza to "hell on earth".
The Hamas-run health ministry updated its death toll in Gaza to 18,412, mostly women and children.
The militant Islamist group said Israeli forces raided a hospital in Gaza City, the biggest urban centre.
"Israeli occupation forces are storming Kamal Adwan hospital after besieging and bombing it for days," health ministry spokesperson Ashraf al-Qudra said, accusing troops of rounding up men in the hospital courtyard, including medical staff.
The army did not immediately comment, but Israel has repeatedly accused Hamas of using hospitals, schools, mosques and tunnels beneath them as military bases — claims it has denied.
The UN humanitarian agency OCHA said earlier that "the hospital remains surrounded by Israeli troops and tanks, and fighting with armed groups has been reported in its vicinity for three consecutive days".
It said two mothers were killed in a strike on the maternity ward, and that about 3,000 internally displaced people were trapped in the facility amid reports of "extreme shortages of water, food and power".
The war began with Hamas's October 7 attacks that killed 1,200 people, according to Israeli figures, and saw around 240 hostages taken back to Gaza.
Israel has responded to the unprecedented attack with an offensive aiming to destroy Hamas that has reduced much of Gaza to rubble.
UN agencies and aid groups fear the Palestinian territory will soon be overwhelmed by starvation and disease, and are pleading with Israel to boost efforts to protect civilians.
Air and artillery strikes again rained down on multiple targets in Gaza, a day after Israeli Defence Minister Yoav Gallant reported significant progress in the war, now in its third month.
"Hamas is on the verge of dissolution — the IDF (Israel Defense Forces) is taking over its last strongholds," he said.
'WWII-level devastation'
The war has deepened the suffering in Gaza, whose devastation top European Union diplomat Josep Borrell has compared to that of Germany during World War II.
The UN estimates 1.9 million of Gaza's 2.4 million people have been displaced by the conflict, half of them children.
Israeli air strikes killed at least 24 people in Rafah near the border with Egypt, where tens of thousands are seeking shelter, the Gaza health ministry said.
One strike left a deep crater and gutted surrounding buildings. Teenagers salvaged belongings from the debris with their hands, a young girl retrieving some notebooks.
"There are still people under the rubble," said resident Abu Jazar, 23. "We call on the Arab people and the world to put on pressure to stop the strikes on Gaza."
At Rafah hospital, bereaved father Hani Abu Jamaa cradled the body of his young daughter Sidal, who was killed by shrapnel.
He said there had been strong explosions overnight and he only found she was dead when he tried to wake her on Tuesday morning.
"Even if I live 100 years, I will never find another like her," he said, crying. "May God have mercy on her, oh Lord."
'No water, no power, no bread'
Israel's military said it had struck a rocket launch site in Jabalia near Gaza City that had fired on Sderot in southern Israel, and also found hundreds of shells and rocket-propelled grenade launchers in a Hamas compound.
The army has lost 105 soldiers in the offensive, it said on Tuesday, including 13 killed by friendly fire and others in accidents.
Fighting and heavy bombardment in south Gaza, where Israel previously urged civilians to seek safety, have left people with few places to go.
In Gaza City, thousands of Palestinians set up camp at a UN agency headquarters after nearby homes and shops were destroyed by Israeli strikes.
An AFP correspondent said both the Islamic and adjacent Al-Azhar universities had been reduced to rubble, as had the police station.
"There is no water. There is no electricity, no bread, no milk for the children, and no diapers," said Rami al-Dahduh, 23, a tailor.
New UN meeting
The UN General Assembly was due to vote later Tuesday on a non-binding resolution demanding "an immediate humanitarian ceasefire".
The draft text, seen by AFP, largely reproduces the resolution blocked by the United States, a key ally of Israel, at a UN Security Council vote on Friday.
"We condemn anyone who encourages Israel to continue its killings," Palestinian prime minister Mohammad Shtayyeh told a cabinet meeting in Ramallah ahead of the vote.
"While claiming to be against the killing of civilians, the United States obstructs the Security Council resolutions to halt the war," he said.
Prime Minister Benjamin Netanyahu said Israel had received the "full backing" of the United States which would block "international pressure to stop the war".
He added, however, that "there is disagreement about 'the day after Hamas' and I hope that we will reach agreement here as well."
Arab countries called the new special session of the General Assembly after more than a dozen Security Council ambassadors visited the Rafah border.
Fears of a wider conflict continue to grow, with Iran-backed groups targeting US and allied forces in Iraq and Syria, and daily exchanges of fire along Israel's border with Lebanon.
France said one of its frigates shot down a drone threatening a Norwegian-flagged tanker hit in an overnight missile attack claimed by Iran-backed Huthi rebels.
