At least four people have been injured in a shooting in the Swedish city of Malmo.

Masked gunmen on mopeds opened fire on a car they had chased through southern Malmo, according to Swedish newspaper Expressen.

The attackers are believed to have fled the scene and police have said they are investigating the incident as an attempted murder.

Eyewitnesses claim around twenty shots were fired as police found shell casings at the scene, the Mirror reported.

“On one moped, there were two masked people and on the other just one person. Both disappeared from the scene after the firing,” a witness told local newspaper Sydsvenskan.

Another witness said she no longer feels safe in the city.

"I like it here, but now I'm really scared. There are loads of kids who live here and are out playing," she said.

There has been an increase in gun crime in Sweden over the past decade mostly attributed to feuds between rival gangs.

Meanwhile fears of a terror attack in the city were raised after an explosion was heard in the suburb of Helenehold only hours after the attack.

The blast was later reported to have been caused by fireworks and it is not yet known if the two incidents are linked.

Bomb disposal experts and police rushed to the area following the explosion.
