Indonesian troops killed five suspected separatist rebels in Aceh province during a raid on a suspected rebel base, a military spokesman said.
The dead were among 12 alleged rebels, including a district commander, whom the military claims to have killed since Sunday.
Major Zaenal Mutaqin, the Aceh military spokesman, said troops found the five unidentified bodies after 98 soldiers attacked a base of the separatist Free Aceh Movement (GAM) in the Raya Baroh region of West Aceh Monday.
Mutaqin said a 30-minute firefight erupted when forces attacked the base which they believed held about 60 rebels. Troops seized an AK-56 rifle and a number of rebel documents, he said. GAM said the victims were civilians.
In a separate incident in South Aceh Monday, troops shot dead Yong Padang, 47, whom they allege was the district GAM commander.
Captain Satria Marmi, who led 11 Indonesian soldiers in the operation, said they shot Padang during a search of Padang Panyang village. He was bathing when he realized his house was surrounded and tried to flee before troops shot him, Marmi said.
Three other suspected rebels died Monday during a joint military-police operation in West Aceh after two paramilitary policemen were wounded during an attack on their post in the Krueng Sabe area, police said.
GAM again said the victims were civilians and also denied that three men killed by government forces on Sunday were rebels. Mutaqin said they died during a 30-minute exchange of fire between 25 soldiers and 80 rebels in the Seunagan area of West Aceh.
Abu Arafah, a GAM district commander, said the military had killed civilians "because they are frustrated they had no success finding GAM." The violence comes after a call by the Indonesian government on Monday for Sweden to take action against exiled GAM leader Hasan di Tiro, who has lived in the country since 1979.
An estimated 10,000 people have died since 1976 when GAM began its fight for independence in the province at the tip of Sumatra island. An Acehnese rights body earlier said 845 civilians have been killed this year alone.
