Israel says the six were killed last August by Hamas just before soldiers reached the site. Autopsies indicate they were shot at close range. Among them was Hersh Goldberg Polin, who had lost part of his arm during the 7 October attack.

The material emerges as talks move into a tougher second phase, with one hostage’s remains still in Gaza.
