Palestinian militant group Hamas said Friday that it has accepted a proposal from mediators to release one living American-Israeli hostage and the bodies of four dual nationals who had died in captivity. The Israeli prime minister's office cast doubt on the offer, accusing Hamas of trying to manipulate talks underway in Qatar on the next stage of the Israel-Hamas ceasefire. Hamas, which rules over what remains of the Gaza Strip, didn't immediately specify when the release of soldier Edan Alexander and the four bodies would take place — or what it expected to get in return. Alexander was 19 when he was abducted from his base on the border with Gaza in southern Israel during Hamas' attack on Oct. 7, 2023 that sparked the war, which has been the deadliest and most destructive fighting ever between Israel and Hamas. It wasn't clear which mediators had proposed the release to Hamas. The United States, led by Trump administration hostage envoy Steve Witkoff, has been pushing for a proposal that would extend the truce and see some hostage-for-prisoner exchanges. Following the Hamas statement, Israeli Prime Minister Benjamin Netanyahu's office said that Israel had “accepted the Witkoff outline and showed flexibility,” but that “Hamas is refusing and will not budge from its positions.”
