The Israeli military ordered Palestinians to evacuate areas in northern Gaza on Sunday before intensified fighting against Hamas, as U.S. President Donald Trump called for an end to the war amid renewed efforts to broker a ceasefire.

"Make the deal in Gaza, get the hostages back," Trump posted on his Truth Social platform early on Sunday.

Israeli Prime Minister Benjamin Netanyahu was due to hold talks later in the day on the progress of Israel's offensive. A senior security official said the military will tell him the campaign is close to reaching its objectives, and warn that expanding fighting to new areas in Gaza may endanger the remaining Israeli hostages.

But in a statement posted on X and text messages sent to many residents, the military urged people in northern parts of the enclave to head south towards the Al-Mawasi area in Khan Younis, which Israel designated as a humanitarian area. Palestinian and U.N. officials say nowhere in Gaza is safe.

"The (Israeli) Defense Forces is operating with extreme force in these areas, and these military operations will escalate, intensify, and extend westward to the city center to destroy the capabilities of terrorist organizations," the military said.

The evacuation order covered the Jabalia area and most Gaza City districts. Medics and residents said the Israeli army's bombardments escalated in the early hours in Jabalia, destroying several houses and killing at least six people.

In Khan Younis in the south, five people were killed in an airstrike on a tent encampment near Mawasi, medics said. At least 12 other people were killed in separate Israeli military strikes and gunfire across the enclave, taking Sunday's death toll to at least 23, medics said.

At Nasser Hospital in Khan Younis, relatives arrived to pay their respects to white-shrouded bodies before they are buried.

"A month ago, they (Israel) told us to go to Al-Mawasi (in Khan Younis) and we stayed there for a month, it is a safe zone," said Zeyad Abu Marouf. He said three of his children were killed and a fourth was wounded in the Israeli airstrike.

"We ask God and the Arabs to move and end this occupation and the injustice taking place against us,” Abu Marouf told Reuters.

NEW CEASEFIRE PUSH

The military escalation comes as Arab mediators, Egypt and Qatar, backed by the United States, begin a new ceasefire effort to halt the 20-month-old conflict and secure the release of Israeli and foreign hostages still being held by Hamas.

Interest in resolving the Gaza conflict has heightened following U.S. and Israeli bombings of Iran's nuclear facilities.

There has also been rising concern over how aid is being distributed to Gazans in the ruined enclave. Hundreds of Palestinians have been killed over the past month in the vicinity of areas where food was being handed out, local hospitals and officials have said.

A Hamas official told Reuters the group had informed the mediators it was ready to resume ceasefire talks, but reaffirmed the group's outstanding demands that any deal must end the war and secure an Israeli withdrawal from the coastal territory.

Hamas has said it is willing to free remaining hostages in Gaza, 20 of whom are believed to still be alive, only in a deal that will end the war. Israel says it can only end the war if Hamas is disarmed and dismantled. Hamas refuses to lay down its arms.

The war began after Hamas attacked Israel on October 7, 2023, killing 1,200 people and taking 251 hostages, according to Israeli tallies.

Israel's subsequent military assault has killed more than 56,000 Palestinians, according to the Gaza health ministry, displaced almost the entire 2.3 million population and plunged the enclave into a humanitarian crisis.
