A Syrian refugee set off an explosion at a bar in southern Germany that killed himself and wounded 12 others late on Sunday, German media agency DPA reported citing the local interior minister.
The 27-year-old man, whose asylum application had been rejected a year ago, had intended to disrupt a nearby pop music festival where 2,500 people had gathered, Joachim Herrmann said, according to DPA.
"An explosion went off in the city centre and a man was killed in the event," police said in a statement.
A dozen people were injured in the explosion, three of them seriously, added a spokeswoman, without giving any more details.
Police have blocked off the city centre and emergency services were on the scene.
Bomb experts were on their way to determine the cause of the explosion.
"The explosion was set off deliberately," said Michael Siefener, a spokesman for the regional interior ministry, adding that authorities were trying to establish the exact cause.
