US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu said on Monday that they had agreed on a plan to end the war in Gaza, but Hamas officials said the group had not received a copy of the plan.

Trump's 20-point plan, released by the White House, calls for all hostilities to immediately end, a swap of hostages held by Hamas for Palestinian prisoners held by Israel, a staged Israeli troop withdrawal from the Palestinian enclave, Hamas disarmament and a transitional government led by an international body.

Trump would chair an international "board of peace" to govern and reconstruct the Gaza Strip as part of the plan, which does not require people to leave Gaza and calls for the war to end immediately if both sides accept it.

Speaking at a joint news conference with Netanyahu, Trump said that it is time for Palestinian militant group Hamas to accept the 20-point peace proposal that he agreed to with Netanyahu regarding the future of Gaza.

"We're not quite finished," Trump said. "We have to get Hamas, but I think they're going to be able to do that. So now it's time for Hamas to accept the terms of the plan that we've put forward today."

Trump said Israel would have the "full backing" of the US to take steps to defeat Hamas if the group doesn't accept the proposed peace deal.

"I support your plan to end the war in Gaza, which achieves our war aims," Netanyahu said.

Shortly after Trump and Netanyahu's news conference, in which neither took questions from reporters, Hamas official Mahmoud Mardawi said that the group has not yet received Trump's written Gaza peace plan.

The official made the remarks in an interview with Al Jazeera Mubasher TV.

A senior Hamas official, Taher a-Nunu, told Al Araby TV on Monday that the group had not received a copy of the plan nor was it involved in its drafting, the hill.com reported on Monday.
