Indonesia church attacks: one family responsible, says police
A family of six, including a nine-year-old girl, were behind a wave of blasts targeting three churches in Indonesia's second city of Surabaya, police say.
At least 13 people were killed and dozens injured in the attacks.
The mother and two daughters blew themselves up at a church, while the father and two sons targeted two others, according to police.
Sunday's bombings, which the Islamic State group has claimed, are the deadliest in Indonesia since 2005.
Police chief Tito Karnavian said the family belonged to an Indonesian IS-inspired network, Jemaah Ansharut Daulah (JAD). Reports suggested the family may have spent time in Syria with IS.
The father drove a bomb-laden car into the grounds of Surabaya Centre Pentecostal Church, police said.
The mother and her two daughters - aged 9 and 12 - had bombs strapped to them and blew themselves up at Diponegoro Indonesian Christian Church.
The family's sons - aged 16 and 18 - rode motorcycles into Santa Maria Catholic Church, and detonated explosives they were carrying. It was their attack that came first, at around 7:30 am local time. The other two attacks followed five minutes apart, police said, according to the Jakarta Post.
Officials reportedly foiled attacks against other churches.
Visiting the scene of one of the bombings, President Joko Widodo described the attacks as "barbaric", adding that he had ordered police to "look into and break up networks of perpetrators".
Also on Sunday, police said they killed four suspected members of JAD in Cianjur, West Java, and arrested two others.
