A rescued 16-year-old hostage helped Philippine soldiers hunt down one of the FBI's most-wanted terror suspects and his accomplice during the final battle against the Islamic State in the southern city of Marawi.
Isnilon Hapilon, IS's 'emir' in Southeast Asia, and Omarkhayam Maute, another leader of the Marawi siege, were killed in gun battle on Monday in a push by troops to retake the last pocket of the city.
A teen hostage who had been rescued by troops provided the crucial information that allowed troops to locate Hapilon and Maute in one building in Marawi.
The US State Department has offered a reward of up to $5million for Hapilon, who Washington blames for ransom kidnappings of several Americans, one of whom was beheaded in 2001 in southern Basilan province.
