Two men were killed and more than 10 were wounded after gunmen burst into a pub firing automatic weapons in a suspected gang-related attack in the Swedish city of Gothenburg.
Customers in the bar were watching football on television when at least two gunmen, reportedly wearing skeleton masks, launched their shooting spree.
“We are assuming that this is gang-related and not a terrorist attack,” police spokesman Bjoer Blixter said.
“We’ve had similar problems with shootings for several years but never of this magnitude.”
A manhunt has been launched for the gunmen who fled by car after the shooting in a heavily immigrant area of Sweden’s second city.
Blixter said two people died and between 10 and 15 were wounded, but the death toll could rise.
Gothenburg police said they have launched a murder investigation and are questioning a large number of people but no arrests have been made.
Sweden and neighbouring Denmark have a longstanding problem with criminal gangs, including Hells Angels, Bandidos and several immigrant groups which battle for control of the local drug trade.
The shooting fitted a pattern of regular tit-for-tat retributions between rival gangs in areas with high immigrant populations in Gothenburg, which lies on Sweden’s southwestern coast and has a population of 550,000.
One witness told the Aftonbladet tabloid that two people entered the pub in Gothenburg’s heavily immigrant suburb of Biskopsgaarden armed with weapons that looked like Kalashnikovs and started shooting.
Another witness said the shootings were over quickly.
“I didn’t have time to think what was happening. Then I saw that my friend was bleeding. I tried to stop the flow of blood as well as I could with my hands,” a man who gave his name as “Rocky” told public broadcaster SVT.
