Afrasianet - At least two people have been killed and several injured in a shooting in a restaurant in the south-western Swedish city of Gothenburg, police say.

They say automatic weapons - believed to be Kalashnikov assault rifles - were used in the attack late on Wednesday.

Police spokeswoman Ulla Brehm was quoted as saying the shooting could have been gang-related.

One witness told Sweden's SVT broadcaster that two men entered the restaurant and opened fire.

The attack happened as customers were watching a football game.

The gunmen are believed to have fled.

The police sealed off the area and launched a murder investigation.
