Police have said "all possible scenarios are being kept open" after officers shot and injured a man who attacked people with a knife at a busy rail station in Amsterdam.

Two people were stabbed at Centraal Station on Friday morning and were joined in hospital by their suspected assailant after armed police were sent to the scene.

No motive has yet been established for the stabbings and it is not known whether the incident was terror-related.

Two platforms were closed to trains and a tunnel under the tracks was also shut, but the station - which is a busy entry and exit point for visitors to the Dutch city - was not evacuated.

However, trams to and from the square in front of the premises were stopped as police and other emergency services converged on the area, which was taped off to keep pedestrians away.

One traveller, Jamie van Gastel, told Dutch newspaper The Telegraaf it was "chaotic" in front of the station, with Friday an especially busy day for visitors arriving ahead of the weekend.

Centraal Station offers services to the city's international airport, Schiphol.

"There were police everywhere - I saw at least 15 cars and a lot of police officers," Mr Van Gastel said.

"A police helicopter also circulated over the the station for a time."
