The stench of death is overpowering from the moment you enter the narrow tunnel.

This is where the leader of Hamas is said to have drawn his last breath, some 26ft below Gaza’s European hospital in the west of Khan Younis.

Mohammed Sinwar was killed here on May 13 in an air strike, Israel has said.

After facing criticism for civilian deaths during the bombing, the military has brought The Telegraph here in an effort to show the attack was part of a precision strike on the terror group.

In a small room off the main tunnel, congealed blood was still visible on the floor beside several dirty mattresses.

Next to a flat-screen television, two Israeli M16 rifles hung on the wall – trophies from the Oct 7 2023 incursion and massacre, Israeli officials said.

On Sunday, the Israel Defence Forces (IDF) revealed what they claim to be Sinwar’s hiding place in a rare and tightly controlled visit inside Gaza.

One officer described the missile attack that reportedly killed him as “a world-class air strike”.
