Authorities say vandals are behind a fire at the Gare du Nord train station in Paris that has halted train traffic to Britain and many other destinations.

The SNCF national rail service says the fire Tuesday was caused by a "malicious incident," without elaborating. A police official said the fire was being investigated but there was no immediate danger to passengers. BFM television reported the fire was in an electrical station.

The incident came amid nationwide jitters following a truck attack in Nice last week that killed 84 people and was claimed by the Islamic State group, the third major attack in France in 18 months.

Eurostar trains across the English Channel and trains to Brussels, Amsterdam and other international destinations all leave from the Gare du Nord in Paris.
