Four suspected separatist rebels and a public transport driver have been killed over the past three days in Indonesia's rebellious Aceh province, the military and residents said.

A local rebel leader identified as Usman bin Rahmad was killed in a gunfight with soldiers at Simpang Nalep in Bireun district on Thursday, Aceh military spokesman Major Zenal Muttaqin said.

Muttaqin said the troops later shot dead another suspected rebel of the Free Aceh Movement (GAM) as he tried to run away. The troops seized two pistols, a hand grenade and a satellite mobile phone and bullets from the rebels.

Separately, troops raided a rebel hideout in the Reunong area of North Aceh district on Thursday, killing a guerilla.

On Friday security forces killed another GAM member in a gunfight at Paya Meuligoe Pereulak in East Aceh.

In another incident, a public minivan driver was shot dead by two men riding on a motorcycle in the provincial capital Banda Aceh on Friday, police and witnesses said. GAM and police accused each other of the killing.

An estimated 10,000 people have died since December 1976 when GAM began its 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.
