A senior Hamas official has told the BBC the Palestinian armed group will reject the latest US proposal for a new Gaza ceasefire and hostage release deal.
The White House said on Thursday that Israel had "signed off" on US envoy Steve Witkoff's plan and that it was waiting for a formal response from Hamas.
Israeli media cited Israeli officials as saying it would see Hamas hand over 10 living hostages and the bodies of 18 dead hostages in two phases in exchange for a 60-day ceasefire and the release of Palestinian prisoners in Israeli jails.
The Hamas official said the proposal did not satisfy core demands, including an end to the war, and that it would respond in due course.
The Israeli government has not commented, but Prime Minister Benjamin Netanyahu reportedly told hostages' families on Thursday that he accepted Witkoff's plan.
Israel imposed a total blockade on Gaza and resumed its military offensive against Hamas on 18 March, collapsing a two-month ceasefire brokered by the US, Qatar and Egypt.
It said it wanted to put pressure on Hamas to release the 58 hostages it is still holding, at least 20 of whom are believed to be alive.
On 19 May, the Israeli military launched an expanded offensive that Netanyahu said would see troops "take control of all areas" of Gaza. The next day, he said Israel would also ease the blockade and allow a "basic" amount of food into Gaza to prevent a famine.
Almost 4,000 people have been killed in Gaza over the past 10 weeks, according to the territory's Hamas-run health ministry.
The UN says another 600,000 people have been displaced again by Israeli ground operations and evacuation orders, and a report by the UN-backed IPC warns that about 500,000 people face catastrophic levels of hunger in the coming months.
