MANILA (2nd UPDATE) — State forces on Tuesday killed 7 members of Abu Sayyaf’s kidnapping group who were aboard a twin engine speed boat in Sulu sea near Sulare island in a gunfight that lasted nearly half an hour, the military said.

The militants were reportedly under Mundi Sawadjaan and Radullan Sahiron, Western Mindanao Command chief Lt. Gen. Corleto Vinluan, Jr. said.

The military's Joint Task Force Sulu released videos showing security forces exchanging fire with the bandits, leading to the extremists' deaths and the sinking of their speedboat.

“Exchanges of fire transpired which lasted for 25 minutes and resulted in the sinking of the boat utilized by more or less seven Abu Sayyaf Group’s members,” Vinluan said.

He added that the slain men from the terror-linked group were planning to conduct kidnap activities in mainland Mindanao. The bandit group is known to be behind the abduction of both foreigners and locals in the area and even in neighboring Malaysia.

“This particular achievement is a result of our united efforts with the people of Sulu particularly our Tausug brothers in bringing lasting peace and development in the province of Sulu," Gonzales said.

Retrieval operations of the sunken speed boat and the bodies of the slain militants are currently ongoing, he said.
