At least six people were injured with one in a critical condition after a knife attack at Paris's international Gare du Nord station early on Wednesday.
The attack took place at 06:42 (05:42 GMT) within one minute all six people were injured and the attacker was stopped.
France Interior Minister Gerald Darmanin said the man was stopped by two off-duty police officers who were returning home from a shift.
He said the suspected attacker was shot three times and taken to hospital with serious injuries, reports BBC.
Authorities are trying to establish if there was a motive for the attack.
Police are yet to name the man, who did not have identity documents on him at the time he was taken to hospital.
