An Israeli man seized in the October 7 Hamas attack was killed on the same day and his body taken to the Gaza Strip, his kibbutz community said, AFP reports.

Tamir Adar was believed to be alive and held in Gaza by Palestinian militants, but the Israeli military has now confirmed that he was killed on the day of the attack, the Nir Oz kibbutz said in a statement.

“The IDF informed the family that he was murdered on October 7, and since then his body has been kept in Gaza,” the statement said.

Adar, 38, was among some 250 people taken hostage from Israeli border communities and military posts. His grandmother was also among them but has been released.
