UN Warns Gaza Faces Humanitarian 'Collapse' As Battles Rage

Artillery fire pounded southern Gaza early Wednesday as Israel said it has begun flooding Hamas tunnels and mediators sought a halt to the nearly four-month war.

The focus of the fighting in recent weeks has been Khan Yunis, the southern Gaza Strip's main city, where an AFP correspondent reported constant air strikes and shelling overnight.

The health ministry recorded at least 125 deaths across the Hamas-ruled territory in the latest Israeli strikes.

UN agency chiefs said a bitter row over the main aid agency for Palestinians could "have catastrophic consequences for the people of Gaza".

Major donors, including Israel's top ally the United States and Germany, have suspended funding to the UN agency for Palestinian refugees, UNRWA, over accusations that several staff members were involved in the October 7 attack that sparked the war.

Withholding the funds was "perilous and would result in the collapse of the humanitarian system in Gaza", the heads of the UN agencies said in a joint statement.

Meanwhile mediation efforts gathered pace following a Sunday meeting of top US, Israeli, Egyptian and Qatari officials that produced a proposed framework for a new truce and hostage release.

A Hamas official told AFP that a delegation headed by the group's leader Ismail Haniyeh "will be in Cairo today or tomorrow (Wednesday or Thursday)" to discuss the proposal.

The war was triggered by Hamas's October 7 attack on Israel, which resulted in the deaths of around 1,140 people, mostly civilians, according to an AFP tally based on official figures.

Militants also seized about 250 hostages. Israel says 132 of them remain in Gaza including at least 29 people believed to have been killed.

Following the deadliest attack in Israel's history, its military launched a withering air, land and sea offensive that has killed at least 26,900 people in Gaza, most of them women and children, according to the territory's health ministry.

The Israeli army said on Wednesday its troops had killed 15 "terrorists" in northern Gaza, and captured 10 militants during a raid on a school where they were allegedly hiding.

In Khan Yunis, where the Hamas government media office said there were "dozens of air raids" overnight, vast areas have been reduced to a muddy wasteland of bombed-out buildings.

According to witnesses, artillery shells hit the area of Nasser Hospital, the city's largest, where the UN humanitarian agency OCHA has said thousands of displaced Palestinians are sheltering.

The Palestinian Red Crescent said on social media platform X that "Israeli shelling and gunfire continue" around another hospital in Khan Yunis.

Staff and patients at the Red Crescent's Al-Amal Hospital "and thousands of displaced people, primarily children and women, live in constant fear and anxiety", it said.

Israel accuses Hamas of operating from tunnels under hospitals in Gaza and of using medical facilities as command centres, a charge denied by the Palestinian group, designated a "terrorist" organisation by the European Union and the United States.

The Israeli military said it had begun flooding the tunnels with water in a bid to "neutralise the threat of Hamas' subterranean network".

An AFP journalist witnessed people fleeing Khan Yunis on Tuesday as explosions sounded nearby.

"We left Nasser Hospital... under tank fire and air strikes. We didn't know where to go," said one woman.

"We're out in the cold, left to fend for ourselves."

Qatar, which helped broker a previous truce and hostage release in November, voiced hope an initial deal now being negotiated might lead to a permanent ceasefire.

The Hamas official said the group is "open to discussing all issues, including prisoner exchange and reconstruction of the Gaza Strip", requesting anonymity due to the sensitivity of the talks.

The official reiterated Hamas's demand for "a comprehensive and complete cessation of (Israel's) aggression" and the withdrawal of its troops from Gaza.

Israeli Prime Minister Benjamin Netanyahu, whose office earlier called the negotiations "constructive", ruled out releasing "thousands" of Palestinian prisoners as part of any deal.

"I would like to make it clear... We will not withdraw the IDF (army) from the Gaza Strip and we will not release thousands of terrorists. None of this will happen," he said on Tuesday.

Violence involving Iran-backed allies of Hamas across the Middle East has surged during the Israel-Hamas war, also drawing in US forces in the region.

President Joe Biden said Tuesday, without offering details, that he had decided on a response to a recent drone strike that killed three US troops in Jordan.

But "I don't think we need a wider war in the Middle East," Biden said. "That's not what I'm looking for."

A pro-Iran group in Iraq, Kataeb Hezbollah, said it would halt attacks on US "occupation forces, in order to prevent embarrassment to the Iraqi government".

The Houthis on Wednesday said they had fired "several" missiles at a US warship, hours after the US military said it had shot down another anti-ship missile over the vital trade route.
