A series of attacks in Indonesia by suicide bombers on churches in the city of Surabaya were suspected to be carried out by the Islamic state-inspired group Jemaah Ansharut Daulah (JAD), a spokesman for the country's intelligence agency saidon 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 involving Islamist militants at a jail near Jakarta last week.
Asked who he thought were the brains behind the attacks, Purwano said: "Still the old group, JAD, who has planned this for some time."
