STOCKHOLM — A truck crashed into an upscale department store in central Stockholm on Friday, ******* at least two people, according to Swedish Prime Minister Stefan Lofven, who said all indications were that it was a ****** ******. One person was arrested.

People in the downtown area fled in panic, and the country’s intelligence agency said a large number of people were *******. Swedish radio put the ***** toll at three.

“Sweden has been attacked,” Lofven said. “This indicates that it is an act of ******.”

Swedish broadcaster SVT said ***** were ***** at the scene, though it wasn’t clear by whom and ****** said they could not confirm that.

Live television footage showed ***** coming out of the upscale Ahlens department store on Drottninggatan Street, which the truck smashed into. The department store is part of Sweden-wide chain. The building includes several stores at street-level.

“We stood inside a shoe store and heard something … and then people started to scream,” witness Jan Granroth told the Aftonbladet daily. “I looked out of the store and saw a big truck.”

Photos from the scene showed ****** truck sticking out of the department store, and Aftonbladet daily reported that Swedish beer maker Spendrups said one of its trucks had been carjacked earlier Friday.

Friday’s ******** is near the site of a December 2010 ****** in which Taimour Abdulwahab, a Swedish citizen who lived in *******, detonated a ******* ****, ******* himself and injuring two others.

Abdulwahab rigged a car with explosives in the hope that the ***** would drive people to Drottninggatan – the street hit Friday – where he would set off devices strapped to his chest and back. The car **** never went off, and Abdulwahab **** when one of his devices exploded among panicked Christmas shoppers.

There was no immediate claim of responsibility for Friday’s ******, but vehicles have been common ******* in recent extremist *******. Last month, in an ****** claimed by the Islamic State group, a man drove into a crowd on London’s Westminster Bridge, ******* three people and injuring many others before stabbing a policeman to *****. A fourth person, a woman thrown into the Thames by the force of the car, **** Thursday.

The IS group has also claimed responsibility for a truck ****** that ****** 86 people in Nice, France, in July and another that ****** 12 people at a Christmas market in Berlin.
