The two boys were part of a group of eight mainly Pacific Islander youths charged with attacking the family, including a 66-year-old father and a 62-year-old mother, and friends walking home from a Sabbath dinner.
I was curious as to the attackers' identities. Were they Muslims who lived in several Sydney neighborhoods I had visited, importing the Middle East conflict Down Under, as they have done in Europe? Not at all. They were local youth, I was told.
Jihad Watch has updated its article if you follow the original link, with the information from Israel Hayom.
