Shots were fired Friday in a major shopping center in Munich and authorities are on the hunt for a gunman, according to reports.

Several people are reported to have been killed, the Sueddeutsche Zeitung is reporting.

Authorities have closed off a wide area around the Munich Olympia Shopping Centre in the Moosach district.

No details were immediately available on injuries or who was responsible for the shooting, a police spokeswoman said.

An official at the shopping center declined comment, saying only, “We are experiencing a problem,” the BBC reported.

Photos from the scene show people fleeing and what appears to be a body on the ground, the Mirror reported.

Security forces have been on high alert after a refugee stabbed five people on a train in Bavaria on Monday.
