From the AP:
A Quebec court clerk has confirmed the names of the suspects in the attack on a Canadian mosque in which six people died. Court clerk Isabelle Ferland identified Alexandre Bissonnette and Mohamed el Khadir as the suspects.
It was also reported that : The shooters yelled "Allahu akbar!" ??
A good guess the motivation is Sunni vs Shia and/or this mosque has become too Westernized.

Sad but Expect the story to disappear since the shooters are probably Muslim believers.
