PARIS, May 9 (Xinhua) -- La Gare du Nord, one of Paris' main railway station, reopened in early Tuesday morning after police evacuated it to search for possible terrorist suspects, the Paris prefecture said.
"End of security checks. Gradual return to normal," Paris police said on its Twitter account.
Police had intervened for operation checks, it said without elaborating.
According to the local news paper Le Parisien, officers, with assault weapons, searched a high speed train arriving from northern France to hunt presumed terrorist militants who were believed to be on board.
An alert about the three suspects was issued by a "partner country" and it was circulated to police last Friday, it added.
France remains top target of terrorist cells due to its military intervention in Iraq, Syria and the Sahel region.
Over the past two years, waves of attacks broke several times the calm at home, with the bloodiest staged at Rivera city of Nice where a man drove his truck into a crowd, killing 86 people on Bastille Day last year.
