The elimination of Yahya Sinwar, Hamas’s top military-terrorist and political chief and the architect of the Oct. 7 invasion—the worst massacre of Jews since the Holocaust—marks a major turning point in the battle to degrade the Iranian-backed jihadist network surrounding Israel.

IDF Spokesperson Rear Adm. Daniel Hagari explained on Thursday that Sinwar had been attempting to flee from house to house, moving between structures in Rafah. Hagari noted that Sinwar “was in flight,” and at one point, after the entourage protecting him had been fired upon by the IDF and split up, Sinwar fled alone into a building.

Sinwar’s death, achieved by fighters from the 450th battalion of the IDF School for Infantry Corps Professions and Squad Commanders (known by its Hebrew acronym, the Bislamach Brigade) occurred in Rafah on Oct. 16.

Two tank shells directed by the force at the building where he was hiding led to Sinwar to first being injured, and then killed by the second shell. In between the two shell strikes, a squad commander with soldiers who attempted to search the building encountered grenades, retreated, and sent quadcopters inside to gather intelligence. One of the quadcopters filmed Sinwar sitting in a room, injured, hurling a plank at the drone (and missing it). The tank shell that eliminated Sinwar soon followed.
