1 dead, 15 injured in Philippines bomb blast

The explosion in Isulan was a short distance from where an improvised bomb under a motorcycle blew up on August 28, killing three and wounding 30. There was no immediate claim of responsibility for Sunday's bombing, but authorities' suspicion immediately fell on the Islamic State-linked Bangsamoro Islamic Freedom Fighters (BIFF).

According to the Philippines government, there are up to 400 BIFF terrorists operating in southern Philippines.
