Filipino soldiers hold on to fleeing children following reports of fresh clashes between government troops and rebels in Marawi City, Mindanao Island, southern Philippines, 25 May 2017. According to media reports, President Rodrigo Duterte declared martial law on the southern island of Mindanao in response to a new armed offensive by the Maute group, one of the jihadist bands operating in the region. On May 23, militants from the Maute group – an organization linked to the so-called Islamic State (or IS or ISIS) – had captured Marawi, a city with a population of 200,000 people, and laid siege on a hospital for hours, and set a church, a college and the city's prison to fire, while holding over 10 people hostage. The Maute group is an Islamic armed organization based in Lanao del Sur that first emerged in 2012 under the name of Khilafah Islamiyah Movement (KIM), but adopted the name EI-Ranao two years later to indicate its affiliation with the so-called Islamic State.

Gun battles between ISIS-linked militants and Filipino troops erupted in Marawi city on Tuesday when gunmen from the local terrorist organizations Maute Group and Abu Sayyaf rampaged through the southern city setting buildings on fire. President Rodrigo Duterte has declared 60 days of martial law in Mindanao as thousands of residents were reported to have fled from Malawi city while at least 21 people were killed, including a police chief who had been beheaded. President Duterte said the influence of Islamic State is one of the nation's top security concerns, and martial law on Mindanao island could be extended across the Philippines to enforce order, allowing the detention of people without charges.
