A gunman has shot and killed multiple people at an outdoor concert in western Austria.

Austrian police said the man fired shots into a crowd, killing two people and injuring 11 others. He then turned the gun on himself, shooting himself.

The shooting occurred near Nenzing in far-western Austria, about 40km east of the border with Liechtenstein.

Police say the overnight shooting was preceded by a loud argument between the gunman and a woman in a nearby parking lot.

They said the man then fetched a gun from his car, left the parking lot, went to the concert venue and started shooting, apparently at random.

Local media quoted rescue workers as saying some of the surviving victims were in serious condition.

Police spokeswoman Susanne Dilp described their wounds as "very diverse".

State broadcaster ORF said the shooting occurred on property used by a motorcycle club.
