Hamas released six hostages from Gaza on Saturday, handing over in two public ceremonies and one private transfer the final living captives in this phase whom the warring sides agreed would be freed when a ceasefire began last month.

In what was set to be the largest swap under January’s ceasefire agreement, six hostages were freed, but the release of some 600 Palestinian prisoners was delayed. It comes after Shiri Bibas’s body was returned by Hamas.

The hostages are the last living hostages to be freed in the first phase of a fragile deal with Israel, adding to pressure for both sides to start negotiations to permanently end the war.
