Iraqis set fire to a French national flag during a demonstration against the satirical French weekly Charlie Hebdo's cartoons of the Prophet Mohammad, in Baghdad January 22, 2015. Charlie Hebdo published a picture of Mohammad weeping on its cover last week after gunmen stormed its offices in Paris, killing 12 people. The gunmen said the attack was revenge for cartoons the magazine had published mocking Islam. REUTERS/Ahmed Saad (IRAQ - Tags: POLITICS CIVIL UNREST MEDIA)
