Lead

Hamas confirmed on Saturday that Izz al-Din al-Haddad, the head of its armed wing, the Qassam Brigades, was killed in an Israeli strike on Gaza the previous day. The confirmation, reported by TASS and Al Jazeera, came after Israeli Defense Minister Israel Katz said on May 15 that al-Haddad had been "liquidated." The strike, which also killed al-Haddad's wife and daughter according to Hamas, occurred amid a broader Israeli operation that killed seven people and wounded dozens more in Gaza City.

Coverage Comparison

Al Jazeera, which provided extensive on-the-ground coverage, reported that at least seven Palestinians were killed in two Israeli air strikes on a residential building and a civilian vehicle. Three women and a baby were among the dead, and dozens were injured, with witnesses describing a "massive fire" and "panic" at the scene. The attack took place on the 78th anniversary of the Nakba, a day of remembrance for the estimated 750,000 Palestinians expelled during the 1948 war.

TASS, citing Hamas's Telegram statement, confirmed al-Haddad's death and added that his wife and daughter were also killed. The Russian agency also noted that Israeli Defense Minister Israel Katz had previously announced the strike, though it did not provide details on the civilian casualties.

Israeli officials, in a joint statement reported by Al Jazeera, said they targeted al-Haddad because he was "one of the architects" of the October 7, 2023, attacks. Their statement did not initially confirm his death, which was later verified by Hamas.

Perspectives

Hamas

Hamas condemned the killing as a "treacherous and cowardly assassination" and an "ongoing aggression against innocent civilians." The group framed the strike as a breach of the ceasefire agreement and accused Israel of demonstrating "the criminal and fascist nature" of its actions, which it said showed disregard for international law.

Israel

Israeli leaders defended the strike, saying al-Haddad was responsible for the murder, abduction, and injury of thousands of Israeli civilians and soldiers. They described him as a key architect of the October 7 attacks, which triggered the current war, and framed the operation as a legitimate act of self-defense.

International Observers

Medical sources and witnesses reported significant civilian casualties, including women and children, raising concerns about the human cost of the operation. The timing of the attack on Nakba Day, a symbolically charged date for Palestinians, added to the sensitivity of the incident. No independent verification of casualty figures or the targeting details was available at the time of reporting.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
