President Donald Trump said he believes Hamas is “ready for a lasting PEACE” after the group released a statement Friday appearing to agree to many of the terms of a peace deal the U.S. and Israel announced this week.

Hamas said in its statement it would release all hostages, including remains of those who have died, and affirmed its “readiness to immediately enter, through mediators, into negotiations to discuss the details.”

It was a potentially major breakthrough after nearly two years of war in the Gaza Strip. Hamas also agreed to hand over control of the Gaza Strip to an independent Palestinian body, an important point in the peace plan.

The group did not agree to disarm or say when it would hand over the hostages, which were also part of the 20-point plan that Trump and Israeli Prime Minister Benjamin Netanyahu proposed.

But in a sign that Trump views this as a good-faith effort on Hamas’ part, he called on Israel in a post on Truth Social to “immediately stop the bombing of Gaza so that we can get the Hostages out safely and quickly,” adding that “we are already in discussions on details to be worked out.”

His post, however, did not say Hamas’ statement was proof of a peace deal, an unusual amount of restraint for the usually boastful president.

Still, should Israel agree to the ceasefire and Hamas release the hostages, the peace deal stands to be the most significant achievement of Trump’s second term.

“This is a big day. We’ll see how it all turns out. We have to get the final word down in concrete,” Trump said in a video later posted to Truth Social. “I just want to let you know that this is a very special day. Maybe unprecedented. In many ways, it is unprecedented.”

Trump in the video thanked the governments of Qatar, Turkey, Saudi Arabia, Egypt and Jordan.

Neither Israel nor Netanyahu immediately issued an official response to the statements from Trump or Hamas.

The peace plan, which Trump and Netanyahu announced during a joint press conference on Monday, lays out conditions for a ceasefire, the exchange of hostages and prisoners and the establishment of an international trusteeship that would govern Gaza in the short-term.

Other elements of the peace deal, Hamas said Friday evening, would require further discussion.

While Trump had called for Hamas to respond to his proposal in “three or four days,” the president on Friday extended that deadline to Sunday, threatening that Hamas would face “all HELL, like no one has ever seen before” if it rejected the offer.

Qatar and other Arab allies have been in close contact with Hamas officials in recent days and urged the group’s leaders to accept the proposal.

Majed Al-Ansari, an adviser to Qatar’s prime minister and the spokesperson for the ministry of foreign affairs, said in a statement posted to X that his country “welcomes the announcement by Hamas of its agreement to President Trump’s plan, and its readiness to release all hostages as part of the exchange framework outlined in the plan.”

He echoed Trump’s calls for a ceasefire “to facilitate the safe and swift release of hostages, and to achieve rapid results that would put an end to the bloodshed of Palestinians in the Gaza Strip.”

Egypt’s ministry of foreign affairs expressed similar support for Hamas’ statement.

“Egypt expresses hope that this positive development will lead all parties to rise to the level of responsibility by committing to the implementation of President Trump’s plan on the ground and ending the war, allowing humanitarian aid to pass through UN mechanisms without restrictions, and releasing hostages and detainees,” it said.
