“Marawi was besieged on May 23, 2017 by hundreds of local and foreign militia waving black IS flags. The Philippine government imposed martial law, and a five-month battle between troops and militants ensued, flattening large parts of the city. The conflict displaced more than 200,000 civilians. Forty-seven civilians were killed in the fighting, with 165 deaths for police and security forces. Official estimates put militants killed in action at 987. “
