Counter-Terrorism Strike Force administration in the Gaza Strip

The Counter-Terrorism Strike Force (CTSF), a Palestinian anti-Hamas armed group, is based in and governs the village of Kizan al-Najjar in the Khan Yunis Governorate of the Gaza Strip. The CTSF, led by Husam al-Astal, had emerged in August 2025 as a rival to Hamas amid the Gaza war and the associated societal breakdown in the Gaza Strip.
