The Philippine military chief says a suspected Indonesian militant has been killed and one of Southeast Asia's top terror suspects is fighting for his life after they were hit in airstrikes in the country's south.

Military chief of staff Gen. Eduardo Ano said Sunday the body of the suspected Indonesian, known by his nom de guerre Mohisen, was recovered by troops along with three Filipino followers of militant leader Isnilon Hapilon, who was seriously wounded in the hilly outskirts of Butig town in Lanao del Sur province.

Ano tells The Associated Press Hapilon was wounded in the arm and was losing blood. Air force warplanes, including South Korean-made FA50 fighter jets deployed in a combat mission for the first time, unleashed 500-pound (225-kilogram) bombs on Wednesday and Thursday.
