Several people were wounded after they were stabbed by a man wielding a knife in Gare du Nord train station in Paris on Wednesday morning.
The man was arrested by police at the station - a busy commuter hub which also serves as a departure point for trains to northern France, London and northern Europe - after they opened fire and wounded him, according to police.
The man attacked several people, including a police officer, with a "bladed weapon" at around 6:43 am local time, French Interior Minister Gerald Darmanin told reporters at the scene.
Several passengers and a border police officer were among the wounded, according to officials. The officer was stabbed in the back by the assailant, but was saved by a bulletproof vest, Darmanin said. Another one of the other victims was seriously injured in the shoulder blade and taken for emergency treatment.
Darmanin thanked the police "for their effective and courageous reaction."
Police cordoned off the station, and set up large white curtains around the attack scene.
The Gare du Nord is one of the world's busiest train stations with 700,000 travellers per day.
The attacker's motive was not immediately clear.
