Muslims, ofcourse, cannot kill other Muslims. All these terrorism acts are reactions to the US policies, plans and investments. Most of these terrorists carry out these terror attacks because they have been brainwashed by propaganda that has been engineered by the US. Why else would any sane person take out his frustration/revenge on innocent fellow civilians?
what about bombing in PAK mosques , karachi killings etc, and in other muslim countries, Would you say bombing which carried and owned by Taliban, AQ, is done by america ....oh man ... one you people even didn't admit that OBL done 19/11 even when he said on video, even then also you say western conspiracy etc etc, OBL is not in PAK etc etc
at the time of any natural clarity all muslim country look toward west for AID and supply.
Stop being an ostrich, tell me which is most advance medical , engg achievement done by any Muslims country.
All Muslims migrated to west because they begain life their after reaching their they fail to achieve decent life why? because of their backwardness and then dream of converting that country into islamist country.
In UK also only Muslims are most backward then other religion people and in US , Europe , communities like Chinese, jews, hindu etc more prosper then Muslims why? ask yourself why?
why no invention take place in any Muslims country,
why their is not big engg construction take place in any Muslims country,
why for refinery you ask foreign engg / country .
Answer is simple , No education / backwardness and that frustration can bee seen , some Muslim people don't want other people to learn and prosper, see Taliban don't want afghan people to right to live.
Taliban , can use video, internet etc but same thing other can't use in name of islam, hypocrisy.
