Hamas released six hostages from Gaza on Saturday. Israel was due to release 620 Palestinian detainees in return, but has delayed the exchange citing further security reviews.

Freed were three Israeli men seized from the Nova music festival and another taken while visiting family in southern Israel during the Hamas-led Oct. 7, 2023, attack that triggered the 16-month war in Gaza. The two others were held for a decade after entering Gaza on their own.

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.
