Philippines — Islamist militancy in Mindanao (Dawlah Islamiya, BIFF remnants)

Low intensity Minor conflict Insurgency Since 29 March 2019 Asia

The 2014 peace agreement with the Moro Islamic Liberation Front ended the main Moro insurgency and created the Bangsamoro Autonomous Region (BARMM), which held its first parliamentary elections on 14 September 2026 after four postponements. Residual Islamic State-aligned factions — Dawlah Islamiya (Maute remnants) and splinters of the Bangsamoro Islamic Freedom Fighters — still mount ambushes and bombings in Maguindanao and Lanao, and the military continues lethal arrest operations: a 28 March 2026 ambush killed five policemen in Shariff Aguak, and clashes in September and October 2026 killed four suspected militants each.

Read these numbers carefully. They are compiled from the sources listed below (UN agencies, conflict-data projects such as UCDP and ACLED, governments, NGOs and news organisations) whose methods differ — some count only documented deaths, others estimate excess mortality. Ranges show the spread between sources; a single figure means only one credible estimate exists. Nothing on this page is a live counter: figures change only when the page is reviewed and rebuilt. Overall confidence in the casualty picture: low.

Background

Origins, phases and the current situation

Moro separatist insurgency in Mindanao began in 1972 under the Moro National Liberation Front. The MILF broke away in 1977 and fought until the 2014 Comprehensive Agreement on the Bangsamoro; the Bangsamoro Organic Law of 2018 created BARMM in 2019 with an MILF-led interim government and a decommissioning process for its roughly 40,000 fighters. Islamic State-aligned groups rejected the deal: the Maute group and Abu Sayyaf seized Marawi in 2017 (a five-month siege), and remnants regrouped as Dawlah Islamiya factions, while the Bangsamoro Islamic Freedom Fighters split into several factions.

Violence has since been low-level but persistent: ambushes on police and soldiers, grenade attacks, the December 2023 Mindanao State University bombing in Marawi (claimed by Islamic State), and clan feuds ('rido') overlapping with militant activity. Military-police operations killed dozens of alleged militants in 2025–2026, including Dawlah Islamiya leaders in Marantao (April 2026) and Sultan Mastura (October 2026). The region's first parliamentary vote, on 14 September 2026, was preceded by a firearms ban during which gun violence actually rose (39 deaths from mid-July to end-August per CEMS monitoring).
