U.S. President Donald Trump on Sunday issued what he called his “last warning” to Hamas, urging the Palestinian militant group to accept a deal to release hostages from Gaza.

“The Israelis have accepted my Terms. It is time for Hamas to accept as well,” Trump said in a post on his Truth Social platform. “I have warned Hamas about the consequences of not accepting. This is my last warning, there will not be another one!”

Hamas said in a later statement that it received some ideas from the United States’ side through mediators to reach a ceasefire deal in Gaza.

The group said it was discussing with mediators ways to develop those ideas, without giving specifics.

Hamas also reiterated its readiness for negotiations to release all hostages in exchange for a “clear announcement of an end to the war” and the complete withdrawal of Israeli forces from the enclave.

Israel’s N12 News reported on Saturday that Trump has put forth a new ceasefire proposal to Hamas.

Under the deal, Hamas would free all the remaining 48 hostages on the first day of the truce in exchange for thousands of Palestinian prisoners jailed in Israel and negotiate an end to the war during a ceasefire in the enclave, according to N12.

An Israeli official said Israel was “seriously considering” Trump’s proposal but did not elaborate on its details.
