NBC  (h/t eran) A lakeside city in the southern Philippines has been rocked by violence after ISIS-linked militants took hostages from a Catholic church and defiantly raised black flags synonymous with the terror group.

The clash in Muslim-majority Marawi, where firefighting erupted Tuesday, has led to at least 44 deaths involving militants, soldiers and police, according to the country’s Armed Forces. Some civilians were reportedly being used as human shields, while others, including children, were evacuated with the help of the military.
