Day 952: IDF Kills Izz al-Din al-Haddad — Head of Hamas Military Wing and 'Last Architect of October 7' in Gaza; Former Captive Hostages Describe 'Closure'

On May 16, 2026 (Day 952 / Ceasefire Day 219), the IDF confirmed the killing of Izz al-Din al-Haddad, the head of Hamas's military wing in Gaza and one of the last surviving senior architects of the October 7, 2023 attack. The precision strike hit a residential building in Gaza City's Rimal neighborhood on Friday evening (May 15), with three Israeli Air Force jets dropping 13 bombs on the target. Six other people were killed alongside al-Haddad, including his wife and daughter; his two sons had been killed in earlier stages of the conflict. Al-Haddad had been a member of Hamas since its founding in the late 1980s, joining the Qassam Brigades' Majd section — originally tasked with acting against Palestinian collaborators — before rising to a seat on Hamas's Military Council, the highest tier of operational commanders who directed the October 7 attacks. IDF Chief of Staff Lt. Gen. Eyal Zamir called the strike 'a significant operational achievement,' stating that al-Haddad's name came up 'time and time again' in debriefing conversations with hostages who returned from Gaza captivity. The IDF said he 'was one of the senior Hamas military commanders who directed the planning and execution' of the October 7 massacres, and had subsequently worked to rehabilitate Hamas's military capabilities and organize further attacks against IDF forces. He had reportedly 'surrounded himself with hostages' as a human shield to deter Israeli targeting during the war. Al-Haddad was the direct captor of five young IDF surveillance soldiers who were kidnapped from the Nahal Oz intelligence observation post on October 7: Liri Albag, Daniela Gilboa, Karina Ariev, Naama Levy, and Agam Berger — all five were released alive in the January 2025 ceasefire phase. Fluent in Hebrew, al-Haddad had extensive personal contact with hostages in his custody, making him well-known to them after their return. Hamas confirmed his death to the Associated Press; his funeral was held in Gaza City on Saturday. Former Israeli hostages expressed profound 'closure,' with one describing him as 'the master murderer.' Prime Minister Netanyahu and Defense Minister Katz issued a joint statement: 'This is a clear message to all terrorists seeking our lives: sooner or later, Israel will reach you.' Al-Haddad's elimination represents the removal of the last known senior Hamas military commander in Gaza directly involved in planning October 7, following the earlier deaths of Yahya Sinwar (killed October 16, 2024), Mohammed Sinwar, Iyad Shambari (head of Hamas Military Intelligence Operations, killed in IDF strike April 29, 2026), and Hamas political chief Ismail Haniyeh (assassinated July 31, 2024, Tehran).
