Three families, including a child as young as eight years old, were involved in ISIS-inspired suicide bombings in Indonesia over the past two days, according to local authorities.

An Indonesian family bought its 8-year-old daughter to a suicide bomb attack it launched Monday on the police headquarters in the country’s second-largest city.

A man, his wife and their children launched suicide attacks on Christians attending Sunday services at three churches in Indonesia. His daughters were aged 12 and 9 while the other two, thought to be the man's sons, were 18 and 16, police said.
