The shooting took place at a fast food restaurant atthe Munich Olympia Shopping Center shortly before 6 p.m. local time (1600 GMT)on Friday, Munich police spokesman Thomas Baumann said.
Twentyothers were also injured in the shooting, which police described as a terrorist attack.
There has been no immediate claim of responsibility for the shooting rampage, but supporters of the Daesh Takfiri group have celebratedthe incident on social media.
There is a major police operation under way in the shopping center, Munich police wrote on its official Twitter account, asking people to stay away from the area. Security forces have also closed off a wide area around the site.
Munich police chief Hubertus Andrae identified the gunman as an 18-year-old German-Iranian man from Munich, who had no criminal record and whose motive was "completely unclear".
Police also said the attackerhad probably carried out the shooting rampage alone and committed suicide, contradicting an earlier statement that three assailants had carried out the attack.
"We found a man who killed himself. We assume that he was the only shooter," police said in a Twitter message.
DPA reported that bomb disposal experts were investigating the backpack of the assailant, whose body was found about one kilometer (0.6 miles) from the mall.
The attackerwas earlier reportedto beheaded for a nearby underground station.
