Hamas said on Friday it was reviewing a U.S. proposal to restore the Gaza ceasefire as Israel intensified military operations in the enclave to press the Palestinian militant group into freeing remaining Israeli hostages.

Hamas said Saturday it will only release an American-Israeli and the bodies of four other hostages if Israel implements their ceasefire agreement, calling it an “exceptional deal”

Israel’s defense minister has ordered the military to take additional parts of the Gaza Strip, and vowed to hold them until Hamas releases the remaining hostages it holds
