Israeli forces relentlessly bombarded areas around two hospitals in Gaza's central southern city, Khan Younis, on Thursday, pinning down large numbers of displaced people, residents said, in an offensive to take Hamas' main stronghold in the enclave's south.
Gaza health officials said at least 50 Palestinians had been killed in Khan Younis in the past 24 hours, including two children in an Israeli air strike that hit a residential home.
The city is now encircled by Israeli armored forces and under almost non-stop aerial and ground fire, residents say.
Palestinian medics said Israeli tanks had cut off. They were shelling targets around the city's two main still-functioning hospitals, Nasser and Al-Amal, trapping medical teams, patients, and displaced people sheltering inside or nearby.
Most of the Gaza Strip's 2.3 million population is now squeezed into Khan Younis and towns just north and south of it after being driven out of its northern half earlier in Israel's blitz of the Hamas-ruled territory, now in its fourth month.
Israeli forces' siege of Khan Younis' main hospitals, which Israel says Hamas militants use as bases for attacks - something the Islamist group and hospital staff deny - have made it near impossible for rescue crews to reach the wounded and dead.
The barrage from advancing Israeli forces forced many displaced people to set out again in search of ever-dwindling places of safe shelter, medics and residents said.
Residents had said on Wednesday that Israeli announcements warning them to leave areas in the line of fire came only after the operation was underway and the main road out of Khan Younis had already shut.
On Wednesday, the United Nations said Israeli tanks struck a large UN compound in Gaza sheltering displaced Palestinians, killing at least nine people and wounding 75. But Israel denied its forces were responsible, suggesting Hamas might have launched the shelling. It said it was reviewing the incident.
Israel said Hamas had "command and control centers, outposts and security headquarters" in the vicinity, which it described as "a dense area" with civilians, as well as the premises of several hospitals where it said militants were active.
At least 25,700 people have been killed in Gaza, one of the world's most densely populated and widely impoverished places, Palestinian health officials say, with large tracts of the heavily built-up enclave flattened by Israeli bombing.
Israel unleashed its war to eradicate Hamas after militants stormed through the border fence in a shock incursion into nearby Israeli towns and bases on Oct. 7, killing 1,200 people and seizing around 240 hostages.
The International Committee of the Red Cross said less than 20 percent of the narrow coastal enclave - around 60 square km (23 sq miles) - was now refuge to more than 1.5 million people in the south "where the dramatic escalation of fighting threatens their survival."
"Every hospital in the Gaza Strip is overcrowded and short on medical supplies, fuel, food, and water. Many are housing thousands of displaced families. And now two more facilities (in Khan Younis) risk being lost due to the fighting. The cumulative impact on the health system is devastating, and urgent action must be taken," the ICRC said in a statement.
Thomas White, director of the UN agency for Palestinian refugees in Gaza, on Thursday, lamented Israel's military operations in neighborhoods teeming with vulnerable civilians.
"Heavy fighting near the remaining hospitals in Khan Younis, including Nasser and Al Amal, has effectively encircled these facilities, leaving terrified staff, patients, and displaced people trapped inside," he said in a statement.
"Al Khair hospital has shut down after patients, including women who had just undergone C-section surgeries, were evacuated in the middle of the night."
In north Gaza, residents said they had almost entirely run out of food, especially flour, and have been grinding down livestock feed to replenish it.
The Israeli military said on Thursday it had killed more than 9,000 Hamas militants and lost 220 soldiers in a 3-1/2-month-old war. Reuters was unable to verify the figures.
In its latest update, the Israeli military said forces had carried out targeted raids with precision air strikes and snipers to take out multiple Hamas command centers and militant emplacements in Khan Younis, including the Al Amal district.
"In close-quarters combat, the soldiers eliminated the terrorists, and various weapons were discovered in the process," it said in a statement.
Israeli forces also raided several militant compounds in central and north Gaza, in one case calling in a helicopter gunship to strike and kill fighters inside, the statement added.
