Israeli planes and tanks pounded the eastern and northern outskirts of Gaza City overnight Saturday to Sunday, destroying buildings and homes, residents said, as Israeli leaders vowed to press on with a planned offensive on the city.

Witnesses reported the sound of explosions non-stop overnight in the areas of Zeitoun and Shejaia, while tanks shelled houses and roads in the nearby Sabra neighbourhood and several buildings were blown up in the northern town of Jabalia.

The Israeli military said on Sunday that its forces have returned to combat in the Jabalia area in recent days, to dismantle militant tunnels and strengthen control of the area.

It added that the operation there "enables the expansion of combat into additional areas and prevents Hamas terrorists from returning to operate in these areas."

Israel approved a plan this month to seize control of Gaza City, describing it as Hamas' last bastion. It is not expected to begin for a few weeks, leaving room for mediators Egypt and Qatar to try and resume ceasefire talks between the sides.

Israel's Defence Minister Israel Katz on Sunday vowed to press on with the offensive, which has raised alarm abroad and objections at home. On Friday Katz said that Gaza City will be razed unless Hamas agrees to end the war on Israel's terms and release all the hostages it still holds.

Fire lit the skies from the direction of the explosions, causing panic, prompting some families to stream out of the city. Others said they would prefer to die and not leave.

'WE ARE NOT LEAVING'

Around half of the enclave's two million people currently live in Gaza City. A few thousand have already left, carrying their belongings on vehicles, and rickshaws.

"I stopped counting the times I had to take my wife and three daughters and leave my home in Gaza City," said Mohammad, 40. "No place is safe, but I can't take the risk. If they suddenly begin the invasion, they will use heavy fire," he told Reuters via a chat app.

Others say they will not leave, no matter what.

"We are not leaving, let them bomb us at home," said Aya, 31, who has a family of eight, adding that they couldn't afford to buy a tent or pay for the transportation, even if they did try to leave. "We are hungry, afraid and don't have money," she said.

A global hunger monitor said on Friday that Gaza City and surrounding areas are officially suffering from famine that will likely spread. Israel has rejected the assessment and says it ignores steps it has taken since late July to increase aid supply into and across Gaza.

On Sunday, the Gaza health ministry said eight more people died of malnutrition and starvation in the enclave, raising deaths from such causes to 289 people, including 115 children, since the war started. Israel disputes fatality figures by the health ministry in the Hamas-run strip.

The war began on October 7, 2023, when Hamas-led gunmen burst into southern Israel, killing some 1,200 people, mainly civilians, and taking 251 hostages.

Israel's military offensive against Hamas has since killed at least 62,000 Palestinians, mostly civilians, according to the Gaza health ministry, left much of the territory in ruins and internally displaced nearly its entire population.
