A manhunt is underway in Sweden after a lorry ploughed into crowds in a shopping area in central Stockholm killing at least three people and leaving several injured.
Armed police rushed to the scene but the driver of the vehicle fled.
All trains in and out of Stockholm have been cancelled for the rest of the day the country's national rail company confirmed.
Sweden’s intelligence agency has said there was a “large number injured” in the attack.
Stefan Lofven, the Prime Minister, said all evidence pointed to “a terror attack”.
Victims were covered with blankets while bloodstains could be seen on pavements near the lorry, which was left halfway inside a well-known department store on Drottninggatan (Queens Street), with its cab on fire.
The lorry, which had been hijacked from the Spendrups brewery earlier in the day, hit pedestrians before crashing into Ahlens Mall.
Glen Foran, an Australian tourist in his 40s, told Reuters he saw the lorry coming.
"I turned around and saw a big truck coming towards me," he said. It swerved from side to side. It didn't look out of control, it was trying to hit people."
"It hit people, it was terrible. It hit a pram with a kid in it, demolished it," he said.
