PARIS -- A French newspaper that published caricatures of the Prophet Muhammad evacuated its offices after receiving a threatening call.
Police say the caller threatened to blow himself up at the offices of France Soir in a Paris suburb (Aubervilliers).
Police sent a team with sniffer dogs.
About 60 employees evacuated the building but were able to go back in two hours later.
Anti-terrorism police are also investigating.
France Soir was the first French newspaper to publish the contested cartoons last week.
The cartoons first appeared in a Danish newspaper.
The caricatures include a drawing of Muhammad wearing a turban shaped as a bomb.
Muslims have been outraged because Islamic tradition bars any depiction of the prophet to prevent idolatry.
