The Israeli military on Sunday released video it said showed the underground rooms where they found the body of Hamas leader Mohammed Sinwar who is believed to have died in tunnels under a Gaza hospital last month.

The Israeli military has confirmed that the body of senior Hamas leader Mohammed Sinwar was found in a tunnel beneath a hospital in Gaza, weeks after he was killed in an airstrike. Sinwar was the younger brother of Yahya Sinwar.

It is believed that Sinwar died from asphyxiation after airstrikes led to the collapse of the tunnel system where he had been taking shelter.
