Three Christian civilians were given shelter by their boss as ISIS-inspired militants went door to door killing non-Muslims in the southern Philippine city of Marawi.

They were hiding in their boss’ basement for weeks before fleeing for their lives at dawn last Tuesday.

Ian Torres, a 25-year-old man who had come to Marawi for a job, said the militants were hunting for Christians and other minority groups door to door.

The militants, local insurgent groups loyal to ISIS, began their attack on the city on May 23, announcing that they intended to create a caliphate in the Philippines’ only Muslim-majority city.

Since the beginning of their assault, the militants have killed more than 300 people, according to Philippine military.

According to their account and other people who have fled the city, a number of local Muslims have been risking their lives to protect their Christian friends and workers.

Weeks ago, another Muslim man gave shelter to 64 Christians in his home as terrorists were hunting for them.

Noor Lucman, a Muslim who lives in Marawi, gave shelter to Christians were working near his home as militants were attacking Marawi, the capital city of about 200,000 people on the Philippine island of Mindanao.

Lucman said after he had fled the city, Christians “couldn't leave the city, so I had to take responsibility in protecting them.”
