“We believe we are dealing with a shooting rampage,” a police spokesman said.
A dead man found one kilometre away from the scene of the shooting had a red backpack.
That bag is similar to that used by the attacker who was outside a McDonald’s restaurant.
A police spokesman said the shootings began in or outside the fast food branch shortly before 6pm local time and were witnessed by up to 100 people.
A woman named Loretta said she was in the McDonald’s when the man with a gun came out of a bathroom and began shooting.
“He’s killing the children. The children were sitting to eat. They can’t run.”
Sky’s Foreign Affairs Editor, Sam Kiley, says one of the suspected gunmen was confronted by a person filming on their mobile phone.
In the video, the attacker can be heard shouting: “I am German – I was born here.”
Employees and customers barricaded themselves inside shops as the attack took place.
But officers believe they have evacuated everyone from the complex and brought them to safety.
An employee who was inside the mall told Reuters by phone that many shots were fired.
The witness said they saw someone who was “so severely injured that he definitely didn’t survive”.
Several highways north of Munich have also been sealed off by police.
There had been reports of a second shooting at the Stachus metro station in the city centre, about five miles away from the mall.
This has been denied by the Munich fire department.
Germany foreign minister Frank-Walter Steinmeier has said the motive for the “abhorrent act” has not been clarified.
He added that investigators have had to contend with “contradictory clues”.
This is the second attack in Germany in less than a week .
On Monday, a 17-year-old Afghan wounded four people in an axe and knife attack on a train near the Bavarian city of Wuerzberg.
