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 Palestinian extremist group Hamas is considering suspending indirect negotiations with Israel. Senior Hamas leader Mahmoud Mardawi wrote on Telegram that the group would not engage in ceasefire discussions until Israel released around 600 Palestinian prisoners who were due to be freed on Saturday.
