MANILA, Philippines (AP) — Philippine troops killed the leader of a small Muslim rebel group and eleven of his men blamed for past bombings and extortion in a clash in the country’s south, military officials said Tuesday.

Seven soldiers were wounded in the hourlong gunbattle Monday against suspected members of the Bangsamoro Islamic Freedom Fighters in a marshy hinterland in Datu Saudi Ampatuan town in Maguindanao del Sur province, Brig. Gen. Jose Vladimir Cagara said.

Cagara said a key commander of the rebel group, Mohiden Animbang, who used the nom de guerre Karialan, was killed, along with his brother, Saga Animbang and 10 other suspected militants. About a dozen of their firearms were recovered from the battle scene.

“This group has long been notorious for bombings, attacking army and police outposts and extortion of bus companies. We finally caught up with them,” Lt. Col. Dennis Almorato, a regional army spokesperson, told The Associated Press by telephone.
