A Syrian migrant was killed when a bomb he was carrying exploded Sunday near a music festival in the Bavarian town of Ansbach, near Nuremberg, officials say. Twelve people were wounded in the blast.
Authorities say the explosion was "intentional" and that the man had tried to commit suicide a few times before Sunday's explosion.
He was denied asylum last year, but was allowed to remain in Germany temporarily.
The blast prompted the evacuation of more than 2,000 people from the music festival.
Earlier Sunday, a machete-wielding Syrian refugee killed a woman and wounded two other people in an attack in the southwestern city of Reutlingen, near Stuttgart.
Germany is still on edge after the killing of nine people by an 18-year-old Iranian-German gunman in Munich Friday.
