When troops killed fugitive Malaysian bomber Mohammad Najib Hussein, alias Abu Anas, in Basilan last December, they disrupted the Abu Sayyaf’s and other terrorists’ training to show support for the Islamic State of Iraq and Syria (ISIS).

Troops also captured the camp where Abu Anas provided training in bomb making and demolition to the Abu Sayyaf band of Isnilon Hapilon, Armed Forces Western Mindanao Command (Westmincom) chief Lt. Gen. Mayoralgo dela Cruz said.

… In a published statement on a web-based news site, Rohan Gunaratna, a Singapore-based counterterrorism expert, warned that the Abu Sayyaf is supporting ISIS in preparation for establishing a local base as seen in the video footage posted last week showing its fighters hoisting the black flag while in training.
