Two people have been killed and three seriously injured in a shooting in a German nightclub, police have said.
Panicked revellers at a nightclub in the lakeside city of Konstanz ran and hid after a gunman opened fire at about 4.30am.
German news agency DPA identified the venue as nightclub Grey, which lies close to the city's airport.
Several media reports in Germany claimed one of the victims was a club-goer.
Police dashed to the scene, shooting and injuring a 34-year-old suspected shooter.
The gunman was rushed to hospital but later died.
He was identified by police as an Iraqi citizen who had been living in Konstanz for some time.
The man, who has not yet been named, was known to the police.
A police officer was injured in the shoot-out but his injuries are not thought to be life-threatening.
Special commando forces and a police helicopter were deployed in the town, which lies close to the Swiss border, as police worked to establish if the gunman acted alone.
Police said the motive for the shooting is not yet clear.
