I'm afraid you guessed wrong. It's terrorism, not Islam. Or would you put down Israel's state terrorist atrocities down to "Judaism"? You'd do well to think a bit if you can before reaching for an easy prejudice.
Islamic State claims responsibility for attack in Paris
Isil has said in a statement, written in French and Arabic, and an audo message claiming responsibility for the attacks, and warning it is the "first of a storm".
They say that France will remain a top target as long as it continues its policies, and the attacks were a response to insults of Islam's prophet and airstrikes in Isil territory.
The statement says that the attackers were "targeting the capital of prostitution and obscenity, the carrier of the banner of the Cross in Europe, Paris".
In the French declaration, Isil said that the goal of the attacks was a "minimum of 200 dead".
It described the attacks "where eight brothers wrapped in explosive belts and armed with machine rifles targeted sites that were accurately chosen in the heart of the capital of France, including the Stade de France during the match between the Crusader German and French teams, where the retard of France, Francois Hollande, was present."
It goes on to say: "[They also targeted] the Bataclan Conference Center where hundreds of apostates had gathered in a profligate prostitution party, and other areas in the 10th and 11th and 18th [arrondissements] and in a coordinated fashion, so Paris shook under their feet, and its streets were tight upon them, and the result of the attacks was the death of no less than 100 Crusaders and the wounding of more than those, and thanks be to Allah."
"And let France and those who walk in its path know that they will remain on the top of the list of targets of the IS, and that the smell of death will never leave their noses as long as they lead the convoy of the Crusader campaign."
It added they "are proud of fighting Islam in France and striking the Muslims in the land of the Caliphate with their planes, which did not help them at all in the streets of Paris and its rotten alleys, and this attack is the first of the storm and a warning to those who wish to learn."
Oh, and by the way...
