The Palestinian terrorist group Hamas officially confirmed on Thursday that its military chief, Mohammed Deif, was killed during the Gaza war, almost six months after the Israel Defense Forces (IDF) reported his death.

Deif, the architect of Hamas’s military capabilities, is believed to have been one of the masterminds behind the terrorist group’s invasion of and massacre across southern Israel on Oct. 7, 2023 — which sparked the Gaza war.

Abu Ubaida, a Hamas spokesperson, also reported the deaths of Deif’s deputy, Khan Younis Brigade commander Rafa Salama, as well as senior operatives Marwan Issa, Ghazi Abu Tama’a, Raad Thabet, Ahmed Ghandour, and Ayman Nofal.

According to the IDF, Deif was killed in an airstrike in Khan Younis in southern Gaza on July 13 of last year.

Following weeks of intelligence assessments, Israeli authorities gathered evidence to confirm Deif’s death before publicly announcing it in early August.

“IDF fighter jets struck in the area of Khan Yunis, and … it can be confirmed that Mohammed Deif was eliminated in the strike,” the military said. “His elimination serves the objectives of the war and demonstrates Israel’s ability to carry out targeted strikes with precision.”

At the time, Hamas neither confirmed nor denied Deif’s death, but one official, Ezzat Rashaq, stated that any announcements regarding the deaths of its leaders would be made solely by the organization.

“Unless either of them [the Hamas political and military leadership] announces it, no news published in the media or by any other parties can be confirmed,” Rashaq said.

In November, the International Criminal Court issued an arrest warrant for Deif, as well as for Israeli Prime Minister Benjamin Netanyahu and his former Defense Minister Yoav Gallant, for alleged war crimes and crimes against humanity related to the Oct. 7 attacks on Israel and the ensuing war in Gaza.

Deif is believed to have collaborated closely with the late Hamas leader Yahya Sinwar, managing military operations and coordinating with the group’s top commanders throughout the conflict.

After Deif’s assassination, then-defense minister Gallant posted an image on social media praising the Israeli military’s accomplishment.

“The assassination of mass murderer Mohammed Deif — ‘Gaza’s Bin Laden’ — is a major step toward dismantling Hamas as a military and governing entity, and achieving the war’s objectives,” he said.
