Two leaders of a militant alliance loyal to the Islamic State group were killed on Monday in clashes with the armed forces of the Philippines in southern Marawi City, the defense minister said on Monday.

Axar.az reports citing Reuters.

“They were killed,” Defence Secretary Delfin Lorenzana told reporters, referring to Omar Khayyam Maute and Isnilon Hapilon. Another rebel commander, Malaysian Mahmud Ahmad, was still at large, he said.

Hapilon is the anointed “emir” of Islamic State in Southeast Asia, and Omar Khayyam Maute is one of two brothers at the helm of the militant group that has been fighting the military since a siege of Marawi City began on May 23.
