A bomb threat has prompted the evacuation of the main railway station in Strasbourg, France. The city has been on high alert after an attack on a Christmas market earlier in December.

Police received a message that an explosive device was present at the station around 6:15 pm on Thursday, local media reported. The station was quickly locked down and the passengers evacuated.

“Ordnance disposal teams are on hand to remove the suspicious package and traffic will gradually resume after their intervention,” the police said.

At 9:01 pm local time, the police gave an all-clear, saying nothing suspicious was found and calling it a “false alarm.”

“Thank you for your patience. Have a good rest of the evening and safe travels to those taking the train,” the police tweeted.

Strasbourg has been on edge since the December 11 attack on the Christmas market, which killed five and wounded 12 people. The attacker, 29-year-old Cherif Chekatt, had pledged allegiance to Islamic State (IS, formerly ISIS/ISIL) before his rampage.
