(HRW) – Coordinated suicide bombings of three Christian churches and the police headquarters in Surabaya, Indonesia’s second largest city, on May 13-14, 2018, were repugnant acts of violence, Human Rights Watch said today. The attackers intentionally used their own children, who were between the ages of 9 and 18, to either carry and detonate explosives or to accompany their parents carrying out the attacks. The bombings killed at least 12 people, plus 13 attackers and their children, and wounded at least 50 others. Three families linked to the Jamaah Ansharut Daulah, an affiliate of the Islamic State (also known as ISIS) in Indonesia, carried out the attacks. The Islamic State claimed responsibility, calling each of the bombings a “martyrdom” operation.
