MANILA - A military helicopter unleashed more rockets on positions held by the rebels in Marawi City on Thursday, marking the 10th day of the crisis that has triggered martial rule in all of Mindanao island.

The airstrike came some 2 hours after the rumble of cannons and gunfire clattered throughout the city.

President Duterte declared martial law in Mindanao on Tuesday last week, when the hardline Maute and Abu Sayyaf laid siege to Marawi after the government attempted but failed to arrest terror leader Isnilon Hapilon.

Government forces have since retaken 90 percent of Marawi, but the rebels had kept up the fight with rifles and ammunition stolen from a police station, a prison, and an armored police vehicle, military spokesman Restituto Padilla said Wednesday.

The crisis has claimed the lives of 129 people, including 89 militants, 21 security forces and 19 civilians.

The government on Wednesday said another rebel group, the Moro Islamic Liberation Front (MILF) had agreed to help get civilians out of Marawi and had accepted Duterte's unconventional offer for communists, separatists and the military to unite against radical Islam. -- With Reuters
