German authorities say two people were fatally shot Wednesday in what appears to be a failed attack on a synagogue on Yom Kippur in the eastern city of Halle. According to The Independent, shots were reported outside the synagogue—where one gunman attempted to break down the doors—and at a nearby kebab shop. In a tweet, local police said two assailants fled the scene in a car; police later confirmed that one suspect has been arrested. “Several shots were fired,” the Halle police said in a statement on Twitter.

Witnesses said one gunman was wearing military camouflage and had several weapons, the BBC reports. Another witness said an explosive—either a Molotov cocktail or a grenade—was launched over a cemetery wall. Police have urged people to stay in their homes. One alleged gunman broadcast his attack on the Twitch live-streaming video platform, where he called himself a Holocaust denier in English.
