It marks the last hostage-detainee exchange between Israel and Hamas carried out as part of the first phase of the U.S.-brokered ceasefire reached in October.

Hamas called Saturday's strikes "a renewed flagrant violation" and urged the United States and other mediating countries to push Israel to stop the strikes.

Israel has appeared to be nonplussed by the committee and has not yet empowered it to work in the half of Gaza that Israel controls.

Israel released 15 bodies of Palestinians killed during its war in Gaza, three days after the remains of the last Israeli hostage was returned.

With all Israeli hostages now recovered from Gaza, there's a push for the Israel-Hamas peace plan to move to phase-two, but that brings its own challenges.

The strikes came a day before the Rafah crossing along Gaza's border with Egypt is set to open, marking a major step in the second phase of the ceasefire.

Israel agreed to return 15 Palestinian bodies for each hostage recovered, according to the ceasefire terms. It’s unclear if the bodies released Thursday were of Palestinian detainees who died in Israeli custody or bodies taken from Gaza by Israeli troops during the war.

A dozen Palestinian returnees were allowed into Gaza from Egypt late Monday night after the long-awaited reopening of the Rafah border crossing was marred by delays.
