A sword-wielding attacker seriously injured a pastor and three other people when he ran into a church service in Sleman, on the island of Java on Sunday 11 February.
Eyewitnesses reported that the attacker damaged Christian imagery and literature, although police have currently stated they do not know the motive for the attack.
The attacker was shot and wounded by police at the scene and then arrested. He was later identified as a university student in his twenties.
Churches in Indonesia have been the targets of multiple terror attacks in recent years. In December 2016, a two-year-old girl who was playing outside the front of a church in Samarinda was killed when an attacker on a motorbike threw explosives at the building.
In December 2017, anti-terror police detained 18 suspects with links to militant groups to reduce the risk of attacks over Christmas and New year.
