JERUSALEM (AP) — A key mediator on Tuesday stressed the urgency of brokering a ceasefire in Gaza after Hamas showed a “positive response” to a proposal, but Israel has yet to weigh in as its military prepares an offensive on some of the territory’s most populated areas.

Israel is studying Hamas' response to a Gaza ceasefire proposal for a 60-day truce and the release of half the hostages still held in the enclave, two Israeli officials said on Tuesday, although one source reiterated that all Israeli captives must be freed for the war to end.

Hamas says it has accepted a proposal from Arab mediators for a ceasefire in the 22-month war sparked by its Oct. 7, 2023, attack into Israel
