I can only say that these Muslims are not following Islamic teachings, otherwise they would have known that killing any innocent Muslim knowingly is one of the greatest of great sins in Islam.<quoted text>
Muslims are bumping off one another on a daily basis in Iraq, Afghanistan, and Pakistan, what have you to say about that? Mossad targets enemies who are a threat to national security and do not target innocent bystanders, Islamists do.
If you do not follow Islamic teachings, the blame is on you and not on Islam.
Islam is a state of belief, not a label which you put on your forehead and then it stays with you, irrespective of what you say or do.
Allah Knows Best.
