Will this unleash another wave of violence in the Muslim world? A French satirical magazine has published cartoons of prophet Mohammad. There's already reaction from the Arab League. It calls the publication provocative and outrageous. But the League has also appealed to Muslims not to turn to violence to show their disapproval. The French government is not counting on the Arab League to control public behavior. Paris says it will close its embassies and French schools in 20 countries on Friday as a precaution.
