Israel had previously agreed to allow Palestinians fully unrestricted access to northern Gaza during an eventual ceasefire, but the Israeli Prime Minister told his negotiating team this week to demand that armed men be barred from northern Gaza as part of any ceasefire and hostage deal, the source said.

The new demand could potentially upend progress in hostage negotiations and raises further questions about Netanyahu’s commitment to Israel’s own proposal for a deal that has become the basis for detailed negotiations.

But a statement by the Israeli prime minister’s office on Sunday cast doubt on whether the deal would progress, laying out several “principles” Israel is not prepared to abandon, including resumed fighting in Gaza “until all of objectives of the war have been achieved.”

Israel launched its war on Gaza nine months ago, in response to Hamas’ October 7 attack that killed 1,200 people and took more than 250 others hostage, according to Israeli authorities. The war has left swathes of the enclave unrecognizable, displaced almost the entire population and killed more than 38,000 people in Gaza, according to the health ministry there. Israel had said it wouldn’t end the war until all hostages are freed and Hamas is eliminated.
