SHOCKING drone footage reveals inside the slain Hamas chief’s sinister terror tunnel lair – directly under a Gaza hospital.

The IDF released footage as it confirmed the recovery of Mohammed Sinwar’s body from a tunnel, three weeks after announcing his elimination in a strike.

Mohammed was the sibling of Yahya Sinwar, the architect behind the October 7 assault, and took over as Hamas’s de facto leader after Yahya’s death last year.

The elusive new chief was eliminated in a massive airstrike on the European Hospital in southern Gaza on May 13.

Footage posted to the IDF’s X account shows the journey down into the tunnels where he died.

It begins outside a building with a large “Emergency” sign, identified by the IDF as the European Hospital in Khan Yunis.

The drone then flies down a narrow gully and into a fortified underground passage.

It is supported by concrete walls, which are lined with electricity cables and illuminated by bulbs.

The drone enters various larger chambers crammed with supplies and signs of living quarters, such as sleeping bags and kitchen ware.

The IDF said: “Mohammad Sinwar was responsible for the deaths of countless civilians. He was eliminated in an IDF & ISA strike on May 13.

“His remains were located under the European hospital in Khan Yunis, further evidence of how Sinwar and Hamas conceal themselves among civilians and deliberately position themselves in civilian zones like hospitals.

“He died the way he lived—underground.”

A separate clip shows four armed IDF soldiers in an underground bunker, which spokesperson BG Effie Defrin claims is “right beneath the European Hospital”.

He said they found “cash”, “weapons” and “ammunition” that were stashed for “cynical use”.

Sinwar took command of Hamas’ military wing after Mohammad Deif was killed last July and later took over the entire terror group after his brother was killed.

He was believed to have been behind the kidnapping of Israeli soldier Gilad Shalit in 2006 – which eventually led to the release of his brother in a prisoner swap.

Sinwar was also named by experts as Hamas’s most senior commander in Gaza alongside Izz al-Din Haddad.

Israel announced his death last month, but now say they have confirmed his identity with DNA tests.

The IDF said at the time it was a targeted hit on “Hamas terrorists in a command-and-control centre” beneath the medical centre.

Netanyahu’s forces are believed to have used bunker-busting bombs to target the underground complex.

The operation also killed Mohammad Shabana, who commanded the Rafah Brigade cell of Hamas, according to Defrin.

He was one of Hamas’s most senior commanders and was instrumental in constructing the tunnels beneath Rafah used to launch the cross border raids of October 7.

Defrin said: “We will dismantle Hamas because we cannot live with this terror organisation right in our backyard, right across our border.”

Hamas has not commented on reports of the death of either Sinwar or Shabana.

Announcing Sinwar’s death to the Israeli parliament, Netanyahu said: “We eliminated tens of thousands of terrorists, Mohammad Deif, Hassan Nasrallah, Yahya Sinwar, Mohammad Sinwar, and seized the Rafah and Morag crossings.

“In the last two days, we’ve been executing a dramatic plan toward the complete defeat of Hamas.

“We’re taking control of their food distribution and money machine. This is what destroys their governing capabilities.

“That’s what we promised.”
