Police poured into Paris' Gare du Nord station late Monday, evacuating passengers from platforms and sealing off the area for several hours in a new security scare to hit the French capital.
Paris police spokeswoman Johanna Primevert told The Associated Press that the operation was aimed at "removing doubt" and ended with no arrests, but she would not say what prompted it. A station employee said the operation focused on a train from Valenciennes in northern France.
The busy station is the terminus of a large suburban and national rail network as well as Eurostar trains from London.
