Seven people were killed and dozens more injured when suicide bombers targeted three churches in between services in Surabaya, Indonesia, on Sunday.
The attacks have been claimed by the Islamic State and were perpetrated by members of a single family: the mother with two daughters, ages 9 and 12, at one church and the father and two sons, ages 16 and 18, at the other two. All six family members died as well, bringing the total death toll to 13. Local authorities said the family was involved in an ISIS-inspired Indonesian group, Jemaah Ansharut Daulah (JAD), and may have traveled to Syria.
Two of the explosions were timed within one minute of each other at different locations. This is the deadliest terror attack in Indonesia since 2005 and the first time children have been used in an attack. Authorities believe it may be linked to a deadly standoff with an inmate at a high-security prison earlier in May.
