A woman has been arrested after 12 people were reportedly injured in a knife attack at Hamburg’s central train station in Germany.
An assailant stabbed people on the platform between tracks 13 and 14, according to police.
They added that the suspect was a 39-year-old woman.
Officers said they “believe she acted alone” and investigations into the attack are continuing.
There was no immediate information on a possible motive.
The fire service said six of the injured were in a life-threatening condition, three others were seriously hurt, and another three sustained minor injuries, news agency dpa reported.
The attack happened shortly after 6pm local time (5pm UK time) on Friday in front of a waiting train, regional public broadcaster NDR reported.
A high-speed ICE train with its doors open could be seen at the platform after the incident.
Railway operator Deutsche Bahn said it was “deeply shocked” by what had happened.
Four tracks at the station were closed on Friday evening, and some long-distance trains were delayed or diverted.
Hamburg is Germany’s second biggest city, with the train station being a hub for local, regional and long-distance trains.
