Israeli ground forces on Sunday battled Hamas militants near Gaza's largest hospital, where health officials said thousands of staff, patients and displaced people remain trapped with no electricity, dwindling supplies and some gunfire coming inside.

Prime Minister Benjamin Netanyahu has rejected growing international calls for a cease-fire unless it includes the release of all the nearly 240 hostages captured by Hamas in the Oct. 7 rampage that triggered the war, saying Israel was bringing its “full force” with the aim of ending Hamas' 16-year rule in Gaza.

Residents reported heavy airstrikes and shelling, including around Shifa Hospital. Israel, without providing evidence, has accused Hamas of concealing a command post inside and under the hospital compound, allegations denied by Hamas and hospital staff.

“We spent the night in panic waiting for their arrival,” said Ahmed al-Boursh, a resident taking shelter in the hospital. “They are outside, not far from the gates.”

The hospital's last generator ran out of fuel on Saturday, leading to the deaths of three premature babies and four other patients, according to the Health Ministry. It says another 36 babies are at risk of dying without electricity.

Health Ministry Undersecretary Munir al-Boursh said Israeli snipers have deployed around Shifa, firing at any movement inside the compound. He said airstrikes had destroyed several homes next to the hospital, killing three people, including a doctor.

"There are wounded in the house, and we can't reach them," he told Al Jazeera television. “We can't stick our heads out of the window.”

Netanyahu asserted to NBC's “Meet the Press” that Israel had offered Shifa Hospital fuel to run generators but “they refused it.” There was no immediate response from the Health Ministry and others including the Red Cross.

Speaking to CNN, Netanyahu asserted that “100 or so” people had been evacuated from Shifa and that Israel had created safe corridors. The military has said troops would assist in moving babies on Sunday, and that it was in contact with hospital staff.

But the Health Ministry has denied claims of evacuees and safe corridors, and people sheltering in the hospital said they were afraid to go outside.

It was not possible to independently ascertain the situation in and around the hospital.

The Health Ministry said there are still 1,500 patients at Shifa, along with 1,500 medical personnel and between 15,000 and 20,000 people seeking shelter.

The Palestinian Red Crescent rescue service said another Gaza City hospital, the Red Crescent-run Al-Quds, is “no longer operational” because it has run out of fuel. Gaza's sole power plant was forced to shut down a month ago, and Israel has barred any fuel imports, saying Hamas would use them for military purposes.

Nebal Farsakh, a spokesperson for the Red Crescent, said 6,000 people, including displaced families, patients, and staff, remained trapped in the hospital.

Alarm was growing. “Decisive international action is needed now to secure an immediate humanitarian cease-fire and prevent further loss of life" amid attacks on health care, the U.N. regional directors of the World Health Organization and others said in a statement, adding that more than half of Gaza's hospitals are closed and the rest are under “massive strain.”

"We do not want to see a firefight in a hospital where innocent people, helpless people, people seeking medical care are caught in the crossfire,” President Joe Biden's national security adviser, Jake Sullivan, told ABC's “This Week.”

Muhammed Zaqout, director of hospitals in Gaza, said the Health Ministry has been unable to update the death toll since Friday as medics are unable to reach areas hit by Israeli bombardment. “The situation is extremely dire,” he said. “Ambulances are unable to reach people under the rubble.”

About 2.3 million Palestinians remain trapped in the besieged territory.

Evacuation windows, but no pauses

Jordanian Foreign Minister Ayman Safadi said Sunday on X, formerly Twitter, that he asked European Union foreign policy chief Josep Borrell to apply the same “legal, moral grounds” for EU support of Ukraine to “define its stand on Israel's war crimes."

The US has pushed for temporary pauses that would allow for wider distribution of badly needed aid to civilians in the besieged territory, where conditions are increasingly dire.

But Israel has only agreed to brief daily periods during which civilians can flee the area of ground combat in northern Gaza and head south on foot along two main roads. Israel continues to strike what it says are militant targets across southern Gaza, often killing women and children.

Dozens of wounded people, including children, were brought to a hospital in Khan Younis after an Israeli airstrike demolished a building in the southern town. Hospital officials said at least 13 were killed.

The war has displaced over two-thirds of Gaza's population, with most fleeing south. Egypt has allowed hundreds of foreign passport holders and medical patients to exit through its Rafah crossing, as well as the entry of some humanitarian aid.

More than 11,000 Palestinians, two-thirds of them women and minors, have been killed since the war began, according to the Health Ministry in Gaza, which does not differentiate between civilian and militant deaths. About 2,700 people have been reported missing and are thought to be trapped or dead under the rubble.

At least 1,200 people have been killed on the Israeli side, mostly civilians killed in the initial Hamas attack. Forty-six Israeli soldiers have been killed in Gaza since the ground offensive began.

About 250,000 Israelis have been forced to evacuate from communities near Gaza, where Palestinian militants are still firing barrages of rockets, and along the northern border with Lebanon.

Netanyahu rejects US postwar vision

Netanyahu has said the responsibility for any harm to civilians lies with Hamas. Israel has long accused the group, which operates in dense residential neighborhoods, of using civilians as human shields.

On Saturday, Netanyahu began to outline Israel's postwar plans for Gaza, which contrast sharply with the vision put forth by the United States.

Netanyahu said Gaza would be demilitarized and that Israel would retain the ability to enter Gaza freely to hunt down militants. He also rejected the idea that the Palestinian Authority, which currently administers parts of the Israeli-occupied West Bank, would at some stage control Gaza. Hamas drove the PA's forces out of Gaza in a week of street battles in 2007.

Secretary of State Antony Blinken has said the US opposes an Israeli reoccupation of Gaza and envisions a unified Palestinian government in both Gaza and the West Bank as a step toward a Palestinian state. Even before the war, Netanyahu's government was staunchly opposed to Palestinian statehood.

The war threatens to trigger a wider conflict, with Israel and Hezbollah militants in Lebanon frequently trading fire along the border. Hezbollah fired anti-tank missiles into Israel on Sunday, and Israel responded with artillery and fighter jets. Israel's power company said workers repairing lines damaged in previous attacks were wounded, and video footage showed two vehicles on fire.
