Battle of Marawi

Battle of Marawi The Battle of Marawi was a five-month urban armed conflict in Marawi on the island of Mindanao, Philippines, between Philippine security forces and militants affiliated with the Maute group and elements of Abu Sayyaf who pledged allegiance to ISIL. The siege began after clashes during an operation to capture Isnilon Hapilon and involved protracted urban warfare, airstrikes by the Philippine Air Force, and street fighting with heavy involvement of Philippine Army and Philippine Marines. The battle drew regional attention from states such as Malaysia, Indonesia, and United States and influenced international debates at forums including the United Nations.

Background

Marawi is located in the province of Lanao del Sur on Mindanao and has historical links to the Sultanate of Lanao and the Moro conflict. Rising activity by the Maute group and Abu Sayyaf followed the collapse of peace talks with the Moro Islamic Liberation Front and while the Bangsamoro Basic Law was under discussion in the Philippine Congress. The pledge of allegiance by Maute and Abu Sayyaf leaders to Abu Bakr al-Baghdadi created concern among analysts at institutions such as the International Crisis Group and the United States Indo-Pacific Command, and attracted foreign fighters reportedly from Indonesia, Malaysia, and elsewhere. Prior clashes in Butig and incidents in Cagayan de Oro highlighted increasing militant mobility across Lanao del Norte and Lanao del Sur.

Course of the Battle

The offensive began on 23 May 2017 after operations aimed at seizing Isnilon Hapilon, culminating in militants overrunning parts of Marawi City and taking hostages near landmarks such as the Mindanao State University campus and the Marawi Grand Mosque. Philippine forces, including units from the 1st Mechanized Infantry Division and the Marine Battalion Landing Team, deployed in a combined campaign with air support from FA-50 jets and Bell UH-1 Huey helicopters. Urban combat featured snipers, improvised explosive devices, and use of buildings such as the Philippine Army Training Command-adjacent structures for fortified positions by militants linked to ISIL. The siege saw phased operations including ground offensives in districts like Lilod Madaya and coordinated assaults backed by artillery and close air support, with commanders such as Eduardo Año and Carlito Galvez Jr. overseeing campaigns to isolate and eliminate leaders like Omarkhayam Maute and Isnilon Hapilon. Reclaimed areas were repeatedly contested, with episodes of clearing operations, targeted strikes, and search-and-destroy missions supported by intelligence from the National Intelligence Coordinating Agency.

Humanitarian Impact and Casualties

The conflict caused widespread displacement of residents in Marawi City and neighboring municipalities including Baloi and Masiu, producing internal refugees who sought shelter in Iligan and Maranding evacuation centers. Humanitarian organizations such as the International Committee of the Red Cross, United Nations Office for the Coordination of Humanitarian Affairs, and NGOs from Malaysia and Indonesia reported civilian casualties, damage to cultural heritage sites like the Marawi Grand Mosque, and shortages of food, water, and medicine. Casualty reports indicated hundreds of militants killed, dozens of Philippine security forces killed, and significant civilian fatalities and injuries, while thousands of homes and commercial properties in barangays including Basak Malutlut and Lilod Madaya were destroyed, prompting international relief appeals to countries including the United States and institutions such as the Asian Development Bank.

Military and Political Responses

The siege prompted Philippine President Rodrigo Duterte to declare martial law across Mindanao under the 1987 Philippine Constitution, authorized by the House of Representatives and monitored by the Senate. Regional security cooperation intensified, with offers of assistance from the United States Armed Forces including intelligence and logistics, and surveillance aid from Australia and France. The battle influenced counterterrorism policies in the Association of Southeast Asian Nations and raised scrutiny of deradicalization programs involving agencies like the Department of Social Welfare and Development and the Department of National Defense. Domestic political debates in the Philippine Congress examined emergency powers, the use of airstrikes in urban areas, and reconstruction funding.

Aftermath and Reconstruction

Following the proclamation of victory on 23 October 2017 after operations resulting in the deaths of key leaders including Isnilon Hapilon and Omarkhayam Maute, efforts shifted to clearing unexploded ordnance and rebuilding infrastructure in barangays such as Basak Malutlut and Lilod Madaya. The government launched rehabilitation programs under agencies like the Department of Human Settlements and Urban Development and the National Economic and Development Authority with funding proposals debated in the Philippine Congress and contributions from the Asian Development Bank and bilateral partners. Trials of captured militants proceeded in courts including the Sandiganbayan-related jurisdictions and issues of compensation for displaced residents were raised in hearings before the Commission on Human Rights (Philippines). Long-term challenges included reintegration of former combatants, restitution of cultural heritage such as the Marawi Grand Mosque, and reconciliation initiatives involving the Bangsamoro Autonomous Region in Muslim Mindanao and civil society actors aimed at preventing recurrence.
