A series of attacks in Indonesia by suicide bombers on churches in the city of Surabaya were suspected to be carried out by the ISIS-inspired group Jemaah Ansharut Daulah (JAD), a spokesman for the country's intelligence agency said on Sunday.

 

Wawan Purwanto, communication director at the agency, also told Metro TV that the attacks were likely to be linked to a deadly prison hostage incident at a jail near Jakarta involving Islamist militants last week.

 

Asked who he thought were the brains behind the attacks, Purwano said: "Still the old group JAD, who has planned this for sometime."
