Following the return of the entire Israeli delegation from Doha, an Israeli official explained: 'This is because Hamas has not responded to the American proposal that Israel accepted, and maintains its refusal. If there is a change and Hamas accepts the proposal - the delegation will immediately depart wherever needed.' The official added that Hamas is demanding guarantees from the Americans regarding a ceasefire, and also demands that U.S. Middle East envoy Steve Wittekof be a signatory to the agreement. According to the official, Hamas also demands that the ceasefire be anchored in a UN Security Council resolution, which is unacceptable to Israel.
