Several people have been shot dead in a shooting at a shopping centre in the German city of Munich, police say.
A big operation is under way. Police are telling people to stay at home and avoid the streets.
Several people have also been injured at the shopping centre in the north-western Moosach district.
Reports speak of one attacker. Some shopworkers are reportedly unable to leave the building.
There is no information about a possible motive for the attack.
The security forces have been on alert after a migrant stabbed five people on a train in Bavaria on Monday.
The authorities had warned of the danger of further attacks.
A man working at a local petrol station told the BBC: "We see just ambulances and it's like firemen and police but all this area is evacuated, all the streets.
"Now [there] are no cars just on the side of the streets. All of the streets are blocked. I see that the people are scared. Everybody are running around."
Public transport is said to have been suspended as the security operation continues.
