Israel says the remains of the final hostage in Gaza have been recovered, clearing the way for the next phase of the ceasefire that stopped the Israel-Hamas war.

Monday’s announcement came a day after Israel’s government said the military was conducting a “large-scale operation” in a cemetery in northern Gaza to locate the remains of Ran Gvili.

The return of all remaining hostages, living or dead, has been a key part of the Gaza ceasefire’s first phase, and Gvili’s family had urged Israel’s government not to enter the second phase until his remains were recovered and returned.

Israel and Hamas have been under pressure from ceasefire mediators including Washington to move into the second phase of the U.S.-brokered truce, which took effect on Oct. 10.
