SURABAYA, Indonesia (Reuters) - The parents of Indonesian children and young adults who took part in deadly suicide bombings in Surabaya had isolated them within a tightly knit circle of militant Islamists, police said on Tuesday.

A family of six killed at least 13 people, including themselves, by bombing three churches in Surabaya on Sunday in the worst militant attack in the world's biggest Muslim-majority country since the bombing of restaurants in Bali in 2005.
