Banda Aceh – At least 14 people have been killed over the past two days in Indonesia's rebellious Aceh province, security officials and aid workers said Wednesday.

A married couple believed to be members of the separatist Free Aceh Movement (GAM) were killed when a grenade they hurled at security forces exploded near them in East Aceh on Monday, said Adjunct Senior Commissioner Gaguk Sumartono, a local police chief. A gun was seized from the couple's house, he said.

Sumartono said police also gunned down a 22-year-old suspected rebel during a raid in East Aceh's Simpang Nenas village on Monday.

A GAM spokesman, Ishak Daud, denied that the three victims were rebels. "We condemn the killings of civilians who have nothing to do with the GAM," he said.

A civilian and a local Muslim leader were found dead in separate locations in East Aceh on Tuesday, an aid worker said. Their bodies were riddled with bullets and marked by signs of torture.

In North Aceh three bodies with gunshot wounds were found on Tuesday, a local paramedic said.

Troops also killed two rebels in separate locations on Monday and Tuesday in West Aceh, local military spokesman Major Ertoto said.

Aid workers said three bullet-riddled bodies were found in two separate locations in West Aceh on Tuesday.

In another incident, a civilian was shot dead by an unidentified person in Bireuen district on Monday, residents said.

An estimated 10,000 people have died since December 1976 when the GAM began to fight for an independent Islamic state in the province on the northern tip of Sumatra island. More than 300 have been killed this year alone in the energy-rich province.
