SWEDEN remains on high alert after four people were injured in a shooting which rocked the city of Malmo.

The gunmen fled the scene while four people were taken to hospital with gunshot wounds, Fox News reported.

The condition of the victims is unknown, however one person is understood to have suffered a head injury.

Swedish police are treating the shooting as attempted murder.

One witness reported the shots were fired from a grey Audi, which drove off from the scene, but others said the suspects may have escaped on mopeds.

Other witnesses told Sweden’s Expressen newspaper the shots were fired in bursts of three rounds.

Witnesses reported hearing 20 gunshots as a football derby was taking place about 7pm local time.

Police spokesman Ewa-Gun Westford told Expressen: “We have an ongoing operation in the area and have a confirmed shootings with more than one injured.

It is not yet known if the two incidents are linked.

However police at the scene of the reported blast site have not confirmed if anything suspicious was found or if an explosion occurred.

Like the country’s other major cities, Malmo has seen a rise in gun violence in the past decade, often connected to feuds between rival gangs, Associated Press reported.

Reports of a possible explosion in Malmo follow the news that a suspicious device was blown up outside a school in the city of Gotherburng earlier in the day.
