Twenty-three troops of the Philippine government and at least 20 rebels of the Abu Sayyaf group were killed in a day of intensive fire-fight in southern Philippine jungles, according to the military source.

Hundreds of troops on August 12 stormed a base of the Abu Sayyaf group in the southern Basilan province.

The fresh encounter centered two remote villages of Ungkaya Pukan and Silangkum in Tipo-Tipo town of southeastern Basilan. Troops also seized dozens of home-made bombs and 13 high-powered firearms in their raid.

The Abu Sayyaf group, comprising almost 400 members, is blamed for a series of terror attacks and kidnappings in the Philippines .

The attack was part of the Philippine army’s campaign to wipe out the Al Qaida- linked Abu Sayyaf group by the end of this year./.
