In an attempt to try to cut the risk of attacks around Christmas and New Year, Indonesian anti-terrorism police have detained 18 people with links to militant groups.
Christians and churches have come under attack by militants in Indonesia over the years.
In 2000 near simultaneous attacks were staged on churches in Jakart on Christmas Eve.
This has led to authorities increasing security at churches and tourist spots during the Christmas period.
Indonesian police chief Tito Karnavian said that there was no evidence of a specific plot and described the detentions as a ‘pre-emptive strike’.
The majority of those detained have links to previous incidents, he confirmed.
Indonesia’s anti-terror laws allow the detention of people for seven days.
