In what appears to be the latest vehicle-based terrorist attack, a truck has rammed people on a street in central Stockholm, according to witnesses cited by Aftonbladet newspaper. The incident took place when a truck is said to have plowed into a department store, causing multiple casualties.

A worker at Ahlens department store said the truck drove into the store’s perfume department. He said an alarm went off inside the store and everyone was asked to leave the building, SVT reported.

A photo posted online shows the truck after it crashed into Åhlens department store, with the caption stating that the vehicle came from a direction in which trucks are not allowed.

Helicopters are circling above the area, a witness told SVT. Footage posted on Twitter shows panicked pedestrians fleeing the scene.

NBC Eyewitness Maria Nathalie was in the department store at the time of the incident. "People started running down the stairs when the fire alarm started," she told NBC News. "And when we came down to the bottom of the building all we could see was a lot of smoke and there was someone who helped us get out on the other side of the building.

There is an unknown number of injured people in the incident, media reported citing Towe Hägg at Stockholm police. Swedish police have said that the Truck incident may be terror related.

Three people have been killed in the incident, Sveriges Radio reported. There were unsubstantiated reports of shots being fired, SR said.
