One person was arrested after two people were shot dead Wednesday in the eastern German city of Halle, police said.
The Bild and Mitteldeutsche Zeitung newspapers reported the shooting took place near a synagogue.
Wednesday marks Yom Kippur, the holiest day of the year in Judaism, when Jews fast for more than 24 hours, seeking atonement.
Several shots were fired and the two then fled in a car, police said in a tweet. They urged residents to stay in their homes.
Police later said one person was arrested.
National rail operator Deutsche Bahn said the main train station in Halle had been closed.
