Abu Sayyaf beheading incidents

Abu Sayyaf was a radical Sunni Islamist group that has aggressively attacked civilians since the 1990s. It was notorious for beheading both military and civilian captives, especially when kidnap-for-ransom demands are not met. The victims included Filipinos, as well as foreign nationals. Abu Sayyaf primarily operated in western Mindanao and the Sulu Archipelago of the southern Philippines.
