Undated : This undated image provided by the Federal Bureau of Investigation (FBI) shows a wanted poster for Isnilon Hapilon, who was purportedly designated leader of the Islamic State group’s Southeast Asia branch in 2016 but has long ties to local extremist movements. Hapilon gained notoriety beyond the Philippines when he allegedly helped Abu Sayyaf kidnap 20 hostages from a Filipino resort in 2001. Philippine security forces on May 23, 2017, raided a hideout in Marawi city in the volatile southern region of Mindanao, in search of Hapilon. AP/PTI
