Amiril Umbra Kato (18 May 1946[2] – 14 April 2015) was the founder of the Bangsamoro Islamic Freedom Fighters (BIFF), a group which seceded from the Moro Islamic Liberation Front (MILF). He joined the MILF after 1985, after he graduated from Imam Muhammad bin Saud Islamic University in Riyadh, Saudi Arabia.[3] Umbra Kato was the Philippines' most wanted man though due to his still official membership in the MILF he was not hunted by the military.[4] However a warrant of arrest was filed against him together with other BIFF members by the Philippine National Police. The Armed Forces of the Philippines, with the MILF, launched Operation Darkhorse in a bid to arrest him in January 2014.
