Eight separatist rebels including a local leader have been killed in fresh clashes in Indonesia's war-torn Aceh province, the military said.

Teungku Ramli Basyah, the Free Aceh Movement (GAM) deputy chief for Pase region, and his bodyguard were killed during a raid in the Keude Geudumbak area of North Aceh on Thursday, said Major General Bambang Darmono, commander of the military operation in the province. He said Basyah, 35, was a deputy of Sofyan Daud, GAM commander for the Pase district in northern Aceh. Daud was not immediately reachable for confirmation.

Both rebels had tried to escape but soldiers had closed all exit points in the area during the raid, Darmono told a press conference. He said soldiers seized a handgun and some ammunition from Basyah. The general said local residents had reported Basyah's activities in the area. Basyah had managed to escape two previous raids. A resident told reporters that the pair had fought for 20 minutes before being killed.

Troops shot dead three suspected rebels in separate clashes in the Samalanga area of Bireuen district on Wednesday and Thursday, said Aceh military spokesman Ahmad Yani Basuki. He said soldiers killed three other guerrillas in South Aceh's Bakongan area and the Tiro area of Pidie district on Wednesday.

Basuki said security forces also arrested 12 suspected rebels in several areas in the past three days.

The military is now in its fourth month of an all-out drive to rid the resource-rich province on Sumatra island of the rebels, who have been fighting for independence since 1976.

Military spokesman Ditya Sudarsono said Friday that as of Thursday troops had killed 845 guerrillas, while more than 1,800 others had been arrested or had surrendered since the offensive began on May 19. The military had lost 39 soldiers and the police 15 officers.

Aceh police say at least 319 civilians have been killed during the same period while 108 have gone missing. They did not say which side was to blame for the civilian deaths.
