At least four people have been injured in a shooting in the German capital, Berlin. The incident took place on Saturday morning.

The injured have been admitted to the hospital. The condition of three of them is critical.

A police spokesman said several people were involved in the shootings in Berlin's Quetzburg district.

The Social Democrat Party (DPA) office is very close to where the shootings took place.

Police said there was no evidence that the incident was politically motivated. They said that nothing has been known about this yet.

Police have launched an operation to find out who was involved in the incident.
