The assassination of Qassam commander Izz al-Din al-Haddad, first reported late on May 15, dominated May 16 coverage from morning to night. Multiple sources confirmed his killing alongside his wife and daughter, with funeral processions drawing massive crowds in Gaza. Hamas officially mourned him and vowed to continue resistance, while also announcing a second round of elections for its leader. In parallel, Israeli violations of the Gaza ceasefire continued, with new strikes killing at least eight. Settler attacks in the West Bank and Jerusalem persisted, including an armed settler detaining a Palestinian as Israeli forces watched. The Fatah conference concluded with election results for its central committee and revolutionary council. Regional stories included the extension of the Lebanon-Israel truce and US-Israeli preparations for potential renewed strikes on Iran.
