Three churches in Indonesia’s second-largest city, Surabaya, were hit in bomb attacks which killed 13 people and injured dozens on 13 May. The bombings are described as the worst terrorist attack in Indonesia since 2005.
According to news reports, one family carried out the attack, although the Islamic State (IS, Daesh) has claimed responsibility. It is alleged that the family belonged to an Indonesian IS-inspired network, Jemaah Ansharut Daulah (JAD) and may have spent time with jihadis in Syria.
Santa Maria Catholic Church was attacked first by two young men believed to be brothers. The men, 16 year-old Firman Halim lahir and 18 year-old Yusuf Fadhil lahir, reportedly arrived on motorcycles and detonated explosives.
