One of the last military commanders involved in the October 7, 2023 attacks was killed Friday night (15/05) in an Israeli bombardment in western Gaza City. Izz al-Din al-Haddad, leader of the Al-Qassam Brigades — Hamas's military wing — was struck along with his wife and daughter, according to both Hamas and the Israel Defense Forces (IDF).

"O Hamas condenou neste sábado (16/05) o assassinato de Izz al-Din al-Haddad, líder das Brigadas Al-Qassam, apontado como um dos principais comandantes militares da organização na Faixa de Gaza. Al-Haddad foi morto pelas forças israelenses durante um bombardeio realizado na noite desta sexta-feira (15/05), na zona oeste da Cidade de Gaza."

Revista Oeste

"As Forças de Defesa de Israel (IDF, na sigla em inglês) confirmaram a eliminação de Izz al-Din al-Haddad neste sábado, 16. O militar era um dos últimos altos comandantes envolvidos de forma direta no planejamento do massacre de 7 de outubro."

The attack occurred on Nakba Day, when Palestinians commemorate the 78 years since the mass displacement caused by Israel's creation in 1948. Hamas condemned what it called a "treacherous and cowardly assassination" in a statement, claiming the attack represents "another violation of the Gaza ceasefire agreement" signed in October 2025.

"O assassinato de Al-Haddad ocorreu no Dia da Nakba, data em que os palestinos recordam os 78 anos do deslocamento em massa provocado pela criação do Estado de Israel, em 1948."

Opera Mundi

"Na nota, o grupo de resistência afirma que o ataque é mais uma violação do acordo de cessar-fogo em Gaza, denunciando a "agressão contínua contra civis inocentes" por parte de Israel."

Al-Haddad had assumed leadership of the Al-Qassam Brigades after Mohammed Sinwar's death in May 2025. Known as the "Ghost of al-Qassam" for his low profile, he had survived several assassination attempts and had a $750,000 bounty on his head. IDF Chief of Staff Lt.-Gen. Eyal Zamir described the operation as a "significant operational achievement."

According to Gaza health authorities, at least seven Palestinians died Friday (15/05) in Israeli airstrikes in Gaza City. The ceasefire between Israel and Hamas, part of the Trump administration's 20-point peace plan, has been described by the UN as "increasingly fragile," with approximately 800 Palestinians killed since its implementation.
