Abu Sayyaf (/ˈɑːbuːsɑːˈjɑːf/ⓘ; Arabic: جماعة أبو سياف; Jamāʿat Abū Sayyāf, ASG),[26] officially known by the Islamic State as the Islamic State – East Asia Province,[27] was a Jihadistmilitant and pirate group that follows the Wahhabi doctrine of Sunni Islam. It is based in and around Jolo and Basilan islands in the southwestern part of the Philippines, where for more than five decades, Moro groups had been engaged in an insurgency seeking to make Moro Province independent. The group is considered violent[28] and is responsible for the Philippines' worst terrorist attack, the bombing of MV Superferry 14 in 2004, which killed 116 people.[29] The name of the group was derived from Arabic abu (أبو; "father of"), and sayyaf (سيّاف; "swordsmith").[30] As of April 2023[update], the group was estimated to have about 20 members,[31] down from 1,250 in 2000.[32] They use mostly improvised explosive devices, mortars and automatic rifles.
The group is designated as a terrorist group by Australia,[13] Canada,[14] Indonesia,[15] Japan,[16] Malaysia,[17] the Philippines,[12] the United Arab Emirates, the United Kingdom[18] and the United States.[19][37] From January 15, 2002, to February 24, 2015,[38] fighting Abu Sayyaf became a mission of the American military's Operation Enduring Freedom and part of the Global War on Terrorism.[39][40] Several hundred U.S. soldiers were stationed in the area primarily to train Filipino troops in counter-terror and counterguerrilla operations, but, following a status of forces agreement and under Philippine law, they were not allowed to engage in direct combat.[41][42][43][44]
