June 8 (UPI) -- 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 announcement comes more than three weeks after the Israel Defense Forces launched an airstrike on a bunker near Gaza European Hospital in Khan Yunis, killing more than two dozen people. The IDF said Sinwar was among the dead and initially announced his body had been found in the days after the May 13 strike.

The IDF said it confirmed the identity of the body using DNA analysis as well as Sinwar's identification cards found in the tunnels. Hamas has yet to confirm Sinwar's death.

In a video posted on X, the IDF showed an underground tunnel and multiple rooms connected to it. In one room, a body can be seen lying on the ground near items such as firearms and clothing.
