A woman was taken hostage in the western German city of Cologne, with police urging people to stay away from the area around the city's main train station.
"We assume that a hostage has been taken, either at McDonald's or at a nearby pharmacy," a police spokeswoman said, adding: "A woman is probably being held but we don't have any further details."
German magazine Focus had earlier reported that several shots appeared to have been fired at Cologne's main train station, which is next to the city's landmark cathedral.

"We are in contact with the man," police spokesman Christoph Gilles told broadcaster n-tv.
"We need to find out what he wants, what his demands are and whether he carries a weapon," he said, adding that police weren't aware of the man's motive.
Gilles said specially-trained officers were talking to the hostage taker, who hadn't been identified.
"We're doing everything to get the hostage out of there unharmed," Gilles said.
German railroad operator Deutsche Bahn said that all train traffic was shut down.
Ambulances and heavily-armed police were lined up in wait behind the train station.
"We have indications that one man is holding one woman, but we haven't been able to really get close," Schulte said.
