The Israeli military confirmed Friday morning that Hamas hostage Hamza Alzayadni was killed in Gaza, days after it had announced his father's body had been retrieved along with unidentified remains from a tunnel in Gaza.

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 body of Youssef Ziyadne, and possibly that of his son, was found after a "complex and difficult operation," an official said.
