The congregation had been inside the church on the island of Sulawesi at the time of the explosion, South Sulawesi police spokesman E. Zulpan told Reuters. He said it was unclear whether body parts at the scene were only from the attacker, Reuters reported.
Father Wilhemus Tulak, a priest at the church, told Indonesian media that the suspected bomber tried to enter the church grounds on a motorbike, but had been stopped by a security guard. Ten people had been wounded in total, some of them seriously, he said.
Security camera footage showed a blast that blew flame, smoke and debris into the middle of the road.
Police did not say who might be responsible for the apparent attack and there was no immediate claim of responsibility.
