Excellent guess infidel Tark! I heard a blip of this on the radio news from ABC. There was no mention by them of any Islamic ethnicity so I just assumed the culprits were white men. (INTENSE SARC)
OTOH, if '24' is to be my guide, then it could have been Muslim, Russian, or Chinese etc who are the culprits.
I heard one blurp say 3 of them were albanians...I think they are the muzzies taking over Kosovo
