Tens of thousands of people rallied in Sydney on Friday night to protest negative media coverage of Islam and the French magazine Charlie Hebdo's depictions of the Prophet Muhammad.
As Australian police reported, 14 demonstrators have been "removed" from the scene of the action for violation of the order, but charges have not been filed.
"Je suis muslim" is a reference to the phrase "Je suis Charlie", which became a worldwide symbol of solidarity with the journalists of the French newspaper, who were killed during an attack on the Charlie Hebdo's office.
