A U.S. envoy has labeled Hamas’s response to a proposed hostage deal as “totally unacceptable.” Amid ongoing negotiations, Hamas is seeking guarantees that discussions will lead to an end to the war with Israel, adding complexity to the peace efforts.

Hamas’ armed wing announced on Saturday that the fate of a US-Israeli hostage included in an Israeli truce proposal remains unknown. Separately, the group released a video showing another captive alive, shedding light on the complex hostage situation amid regional tensions.
