The Bangsamoro Islamic Freedom Fighters (BIFF) led by Ameril Umbrakato has pledged to join the fight of the Moro National Liberation Front (MNLF) against the Bangsamoro Basic Law (BBL) that seeks to create a new entity that will replace the Autonomous Region in Muslim Mindanao.

MNLF founding chairman Nur Misuari has rejected the BBL because he said it will only create more problems in Mindanao.
