Hamas Warns Gaza Ceasefire 'Could Collapse' After Israeli Raid Captures Its Internal Security Chief

September 2, 2026 — Hamas's internal-security arm (Al-Majd al-Amni) warned that the already-shaky Gaza ceasefire could break down completely following the Sept. 1 Israeli special-forces raid that captured Moein Muhammad al-Arabeed, the group's internal-security chief, in Gaza City's Katiba area; the daylight operation was accompanied by strikes that Gaza's Hamas-run health ministry said killed 3-4 Palestinians. Hamas called the raid a deliberate attempt to 'undermine the ceasefire agreement, sabotage efforts to complete its implementation and create conditions for the continuation of the war.' Political analyst Emad Omar, cited by The National, said the operation 'could make the movement hesitant' to proceed with the disarmament provisions central to the ceasefire's second phase. Defense Minister Israel Katz defended the raid as Israeli 'policy: We do not wait for threats' — deepening the standoff described in Netanyahu's separate Yellow Line remarks the same day.
