Indonesian security forces say they have killed three more suspected militants linked to the country's most wanted Islamic radical.

Central Sulawesi police chief Brig. Gen. Rudy Sufahriadi said Friday that two men were fatally shot in a clash Wednesday near Siliwanga village in Poso district. He said a body believed to be another militant killed in an earlier clash was also discovered in a river.

Earlier this week, police killed two suspected Chinese Uighur militants who were also believed to be linked to Indonesia's most wanted militant, Abu Wardah Santoso, who leads the East Indonesia Mujahidin network that has pledged allegiance to the Islamic State group.

Sufahriadi said security forces are guarding some areas of Poso district to try to prevent members of the network from escaping.
