At least eight people have been killed and 12 wounded in attacks in the religiously-divided Indonesian province of Sulawesi, police say.
An unconfirmed report quoting a police officer said all the victims were Christians.
The attacks by unidentified gunmen occurred in villages near the town of Poso, and come two days after two Christians were killed in another raid.
The latest deaths have raised fears of a resurgence of religious violence in the region, where hundreds of people have been killed since 1999.
Sporadic clashes between Muslims and Christians have continued on Sulawesi, despite the signing of a peace agreement in 2001.
More than 80% of Indonesians are Muslim. But in certain parts of the country, such as central Sulawesi, the number of Christians matches that of the Muslims.
On Friday, armed men attacked a village in the province, killing two Christians.
Like the neighbouring Molucca islands, Sulawesi was ravaged by sectarian violence during the 1999-2001 presidency of Abdurrahman Wahid.
His successor, Megawati Sukarnoputri, has brought relative calm to the region.
