On 23 May 2017, known Islamic terrorist Isnilon Hapilon was reported to be in western Mindanao to meet with Omar and Abdullah Maute, leaders of the Islamic State–affiliated Maute group. The Armed Forces of the Philippines (AFP) and Philippine National Police operation to arrest them set in motion a chain of events that thrust the previously little known Philippine city of Marawi into the global spotlight. This raid rapidly escalated into an urban battle that lasted for five months, involving more than 6500 Philippine military personnel. The fighting resulted in the devastation of a major city and the deaths of over 900 insurgents, at the cost of 168 AFP and security services personnel killed and over 1400 wounded.
