On 23 May 2017, the siege in Marawi City begun when the Islamic State-inspired group known as Maute Group invaded the city and clashed with the government security forces. Martial Law was declared on that same day following a jail break and burning of cathedral and school. In October 2017, this month-long siege came to an end when the Philippine government called off the conflict. The urban gunfight between the group had caused devastating damages not only to the city, but also to the lives of its people.
Majority of the residents fled the city on 24 May 2017 to seek safety in the neighboring towns in the Provinces of Lanao del Norte, Lanao del Sur and Cagayan de Oro City, while some of the residents sought refuge with their relatives in metropolitan cities such as Cebu, Davao, and Manila, as well as in other parts of the country.
