The six Israelis were the last living captives set to be released in the first phase of the cease-fire. The agreement, strained for weeks, has an uncertain future.

Hamas has said it won’t release the remaining captives without a lasting ceasefire and full Israeli withdrawal from Gaza. Netanyahu, with the backing of U.S. President Donald Trump's administration, says he’s committed to destroying Hamas’ military and governing capacities and returning all hostages, goals widely seen as mutually exclusive.

The Israeli military says the sixth and final hostage was released by Hamas in the latest exchange on Saturday and has arrived back in Israel even as heightened tensions clouded the future of the fragile ceasefire deal.
