A major police operation is underway at a shopping mall in Munich, Germany, on Friday after gunshots were heard, according to German media outlets.
A spokesperson for police in Munich described the incident as a "possible terror attack" while speaking to a German radio station.
"At the moment we have a major police operation" at the Olympia-Einkaufszentrum mall," Munich police said in a tweet. "Please avoid the area around the mall."
The Associated Press, citing police, say that several people are dead.
Citing police, German publication TZ.de reported that "one or more" suspects are still at large.
" There were several injured," Munich police tweeted, adding that people should "avoid public spaces in Munich" and that "the situation is even more confusing."
A spokeswoman for the police told German media Bild: "It's probably something bigger."
An area around the shopping area in the district of Moosach was sealed off, the BBC reported.

There has been no description of the shooting suspect.
Some German media are reporting multiple fatalities, but details remain sketchy.
