Cairo/Gaza/Jerusalem: At a funeral in Gaza on Monday a line of Palestinians touched white shrouds containing the bodies of at least 70 people who Palestinian health officials said were killed by an Israeli airstrike targeting Maghazi in the centre of the besieged strip.

It came after one of the enclave's deadliest nights in the 11-week-old battle between Israel and Hamas. One man hugged a dead child and others were hysterical. "The strikes were at 2. The walls and the curtains fell on us," said one man. "I reached down to my four-year-old child but all I found were rocks."

Strikes that began hours before midnight persisted into Monday. Palestinian media said Israel stepped up air and ground shelling in central Gaza with local residents saying they had lived one of their worst nights since the war began.

Health ministry spokesperson Ashraf Al-Qidra said many of  those killed at Maghazi were women and children. Eight others were killed as Israeli planes and tanks carried out dozens of air strikes on houses and roads in nearby al-Bureij and al-Nusseirat, health officials said.

Medics added that an Israeli airstrike in Khan Younis in southern Gaza killed 23, bringing total Palestinian fatalities overnight to more than 100. 

Several residents made pleas on social media for people to afford them shelter as they have become homeless after leaving their homes in Bureij.

“I have 60 people in the house, people who arrived at my house believing that central Gaza area was safe. Now we are searching for a place to get to,” said Odeh, a resident of the refugee camps.

The Israeli army said it was reviewing the report of a Maghazi incident and was committed to minimising harm to civilians. Hamas denies the Israeli charge that it operates in densely populated areas or uses civilians as human shields.

The Palestinian Red Crescent published footage of wounded residents being transported to hospitals. It said Israeli warplanes were bombing main roads, hindering the passage of ambulances and emergency vehicles.

Hamas and smaller militant ally Islamic Jihad, both sworn to Israel's destruction, are believed to be holding more than 100 hostages from among 240 they captured during their Oct. 7 rampage through Israeli towns, when they killed 1,200 people.

Since then, Israel has besieged the narrow Gaza Strip and laid much of it to waste, with more than 20,400 people confirmed killed, according to authorities in Hamas-ruled Gaza, and thousands more believed dead under the rubble. 

The vast majority of the 2.3 million Gazans have been driven from their homes, and the United Nations says conditions are catastrophic.

Since a week-long truce collapsed at the start of the month, fighting has only intensified on the ground, with war spreading from the north to the full length of the densely populated strip.

The Israeli military said on Monday that two of its soldiers had died in the past day, bringing to 158 the number killed since ground operations began on Oct. 20.

A day earlier Prime Minister Benjamin Netanyahu had acknowledged the "heavy cost" but said there was "no choice" but to continue to fight deeper into Gaza until "total victory" over Hamas.

Israel has been under pressure from its closest ally the United States to shift operations to a lower-intensity phase and reduce civilian deaths.

On Saturday, Israel's military chief of staff said his forces had largely achieved operational control in the north of Gaza and would expand operations further in the south.

But residents say fighting has only intensified in northern districts.

Diplomatic efforts, mediated by Egypt and Qatar, on a new truce to free the remaining hostages held in Gaza have yielded little public progress, although Washington described the talks last week as "very serious".

Netanyahu was due to attend a parliamentary discussion of the issue on Monday afternoon and then to convene a session of his war cabinet, Israeli officials told Reuters. 

Islamic Jihad said a delegation led by its exiled leader Ziad al-Nakhlala was in Cairo on Sunday. His arrival followed talks attended by Hamas chief Ismail Haniyeh in recent days.

The militant groups have said they would not discuss any release of hostages unless Israel ends its war in Gaza, while the Israelis say they are willing to discuss only a pause in fighting.
