IDF and Shin Bet Kill Mohammed Sinwar and Two Hamas Brigade Commanders in Tunnel Beneath Gaza European Hospital

The IDF and Shin Bet confirmed on May 13, 2026 (Day 945 of the war) that they killed Mohammed Sinwar — Hamas's top military commander for the Gaza Strip and younger brother of slain Hamas supreme leader Yahya Sinwar — in an airstrike targeting a Hamas command and control center located approximately 8 meters beneath the EU-funded Gaza European Hospital compound in Khan Yunis. Two additional senior Hamas commanders were killed in the same tunnel strike: Muhammad Shabana, commander of the Hamas Rafah Brigade, and Mahdi Quara, commander of the South Khan Yunis Battalion. The IDF said the tunnel served as a command hub used by senior military leadership to plan and direct ongoing operations during the renewed campaign. The Sinwar family has been decimated by Israeli targeted killings: Yahya Sinwar (Hamas supreme leader, architect of October 7) was killed on October 16, 2024 in Rafah; Mohammed had subsequently assumed de facto operational command of Hamas's military arm in Gaza. Israeli officials described Mohammed Sinwar as having been the single most dangerous remaining Hamas military figure after his brother's death. The strike used precision munitions against the tunnel shaft from the surface. The hospital compound was an EU-funded facility; the IDF cited the principle that Hamas's use of protected sites for military infrastructure negates their protected status. Hamas did not immediately confirm the killings. This is the most significant Israeli targeted killing since Yahya Sinwar's death in October 2024.
