An Israeli airstrike in Gaza killed Izz al-Din al-Haddad, the leader of Hamas’ military wing, one of the last surviving architects of the October 7, 2023 attacks that triggered the war in Gaza, the Israeli military said on Saturday.

Al-Haddad’s killing comes as the ceasefire between Israel and Hamas remains fragile. Despite the ceasefire, which went into effect in October, Gaza has seen near-daily Israeli fire with more than 850 people being killed since then.
