Sofia Petkar and Lizzie Stromme report at the UK Express:
The vehicle drove into crowds on Drottninggatan (Queen Street) -- one of the city's major pedestrian streets, just before 3 pm local time, before crashing into Åhlens Mall.
A number of people have been injured, with unconfirmed reports of at least three people killed.
Stockholm police confirmed they are dealing with the incident -- which is being treated as a suspected terror attack according to local media.
Armed police remain on the scene, and the area has been cordoned off.
"Reports have also emerged of a secondary incident -- a shooting -- in a separate area of the city," according to Express.
