An Israeli soldier seized by Hamas fighters during their October 7 attack was killed the same day and his body is being held in Gaza, the army and a campaign group said according to AFP.

The Israeli army confirmed the death of Sergeant Oz Daniel, 19, while the Hostages and Missing Families Forum said his remains are held in the Palestinian territory.

“Oz’s body is still held captive by Hamas,” the forum said in a statement.

Daniel was a guitar player who “believed in the power of music to change the world,” the forum said.
