Almost 125 people have been injured, many seriously, as two Dutch commuter trains crashed head-on in Amsterdam this evening, police said.
There were no immediate reports of fatalities, but of those injured, 13 suffered major injuries while 43 or 44 were badly injured, a spokesman said. About 70 suffered minor injuries.
A trauma helicopter was used to bring the injured to hospital, a spokesman for railways group NS said.
Some people were lifted from the wreckage by cranes while others were led away from the crash site in protective wraps to dozens of waiting ambulances, while police cars and fire trucks stood by.
One of the trains involved in the crash serves the cities of Den Helder and Nijmegen, while the other runs between Amsterdam and Uitgeest, the railways spokesman said.
Netherlands public broadcaster NOS aired video footage showing two trains that had collided.
"We heard a loud bang. I went outside and saw people on the street in panic," a woman at the scene told broadcaster AT5.
"We then saw what had happened. Quite quickly there were emergency services at the scene. It was managed well. Some people had head wounds, others were limping."
