An Indonesian soldier and two civilians were killed in the restive province of Aceh, the military and residents said.

Three other soldiers were injured in a grenade attack. Two men believed to be members of the separatist Free Aceh Movement (GAM) gunned down a soldier in Kuta Blang near the North Aceh district capital of Lhokseumawe late Sunday, Aceh military spokesman Major Zaenal Muttaqin said Monday. The victim and two assailants were all riding motorcycles, he said.

Also Sunday, villagers in Kandang, in North Aceh district, found the bodies of two unidentified men. Both had gunshot wounds, residents said.

Meanwhile, three soldiers who were shopping at a market in Panton Labu, in North Aceh district, were wounded Monday after two unidentified men threw a grenade at them, Muttaqin said. Local GAM spokesman Teungku Jamaika claimed responsibility for the grenade incident.

More than 10,000 people are estimated to have died since 1976 when GAM began its fight for independence in the province at the tip of Sumatra island. An Acehnese rights body has said some 1,000 civilians have been killed this year alone.
