A Syrian asylum-seeker wielding a machete left one woman dead and two other people injured in the German town of Reutlingen, near Stuttgart.
According to the BBC, the attack arose out of argument between the man and the woman. Police arrested the attacker, a 21-year-old man, and do not believe the killing was an act of terrorism.
The woman who was killed worked at a kebab outlet close to where the argument took place, the Bild newspaper said.
Police added that the man arrested had been involved in previous incidents where he had caused injury, but gave no further details.
The incident marks the second act of deadly violence to occur in Germany in the past 48 hours. On Friday, a teen gunman opened fire on a shopping mall in Munich killing 10, including himself. He has since been identified as Ali David Sonboly.
