A man deliberately drives a hijacked truck into a crowd of people in Stockholm, Sweden, killing five people and injuring fifteen others.

On 7 April 2017, a vehicle-ramming terrorist attack took place in central Stockholm, the capital of Sweden. A hijacked truck was deliberately driven into crowds along Drottninggatan before being crashed into an Åhléns department store. Five people were killed and 14 others were seriously injured.

Stockholm is the capital and most populous city of Sweden, as well as the largest urban area in the Nordic countries. Approximately 1 million people live in the municipality, with 1.6 million in the urban area, and 2.5 million in the metropolitan area. The city stretches across fourteen islands where Lake Mälaren flows into the Baltic Sea. Outside the city to the east, and along the coast, is the island chain of the Stockholm archipelago. The area has been settled since the Stone Age, in the 6th millennium BC, and was founded as a city in 1252 by Swedish statesman Birger Jarl. The city serves as the county seat of Stockholm County.

April 7 is the 97th day of the year in the Gregorian calendar; 268 days remain until the end of the year.
