PARIS - Police gradually began reopening Paris' Gare du Nord train station on Monday night after earlier evacuating the platforms and cordoning off the area because of a security alert, local police authorities said. A Reuters witness at the scene said there were at least 10 police vans outside the station in central Paris. 'End of verifications. Gradual return to normal,' Paris police said in a tweet. Authorities gave no other details about the nature of the operation.
