cPolice say they are investigating a “deliberate” attack after a truck drove into pedestrians in Stockholm, killing two people and injuring many more.
Swedish Prime Minister Stefan Lofven says everything indicates the incident is “a terror attack”.
He also says one person has been arrested over the attack.
Swedish broadcaster SVT says shots have been fired in the area, although security services are yet to confirm.
There are also reports of a separate shooting incident in a second location about 20 minutes from the pedestrian shopping street of Drottninggatan, where the crash took place.
The Irish embassy in Sweden says it is aware of “an ongoing incident in central Stockholm”.
It is advising all citizens to remain in a safe place indoors.
According to the Swedish paper Aftonbladet, one eye witness in the shopping mall said she saw “hundreds of people” running for their lives
Another witness described the panic, saying: “I went to the main street when a big truck came out of nowhere. I could not see if anyone was driving it but it got out of control. I saw at least two being run over. I ran as fast as I could from there.”
Others reported hearing screams and seeing “a huge truck” crashing into the wall of a shop in the Åhléns Mall.
Armed police have now cordoned off an area, and police cars, helicopters and ambulances are at the scene.
Local journalist Peter Wolodarski explains what seems to have happened.
“The lorry driver first drove into people on Drottninggatan – which is one of the main central streets in the city.
“A mainly pedestrian street and a main shopping area of central Stockholm.
“It then drove into the big department store, Åhléns” he said.
