Israeli soldiers recovered the body of a 53-year-old hostage in an underground tunnel in southern Gaza, the military said Wednesday, and the army was determining if another set of remains belongs to the man's son.

The hostage, Youssef Ziyadne, an Arab Bedouin, was seized along with three grown children on Oct. 7, 2023. Two of them were released, but there is “serious concern” about the fate of the third.

Yousef Al-Ziyadnah, 53, who was kidnapped during the Hamas attack on Israel on October 7, 2023, was found dead in a tunnel in the Rafah area, a statement from the Israel Defense Forces said. The IDF said he had been “killed in captivity” and confirmed that the dead bodies of at least two Hamas operatives were found nearby.
