The United States is studying Hamas's response to a ceasefire proposal and will discuss it with allies in the Middle East in the coming hours, State Department spokesperson Matthew Miller told reporters on Monday. An Israeli official said no ceasefire agreement had been reached despite the Palestinian militant group Hamas saying on Monday it had accepted a proposal from Egyptian and Qatari mediators after weeks of stop-start talks on a deal for a temporary pause in fighting and the release of hostages to Israel.
