Assailants stabbed a Christian worshipper in the stomach and pounded a minister in the head with a wooden plank as they headed to morning prayers Sunday outside Indonesia's capital.
Neither of the injuries appeared to be life-threatening.
No one claimed responsibility for the attacks. But suspicion immediately fell on Islamic hard-liners who have repeatedly warned members of the Batak Christian Protestant Church against worshipping on a field housing their now-shuttered church.
