At least two people have been killed in a shooting in the eastern German city of Halle, police say.
One person was arrested, police said, but other suspects were believed to have fled the Paulus area in a vehicle.
Witnesses said one gunman was wearing military camouflage and carrying several weapons.
A second shooting was then reported in Landsberg, some 15km (9 miles) east of the city. It was not clear if the incidents were connected.
A witness told German n-tv news that a gunman in camouflage opened fire with an assault rifle on a doner kebab shop.
“The man came up to the Doner shop, he threw something like a grenade, it didn’t explode, and he opened fire with an assault rifle. The man behind me must have died… I hid in the toilet,” the witness told a TV reporter near the scene.
German media report that shots were also fired near a synagogue in Halle, but the details have not been confirmed.
One witness said one attacker had thrown a petrol bomb or grenade over a cemetery wall. It happens as Jews celebrate Yom Kippur, Judaism’s holiest day.
It was not clear where the arrest took place. Police are still warning residents to remain in their homes.
