A car with slogans scrawled on its sides crashed into the gate of the office of German Chancellor Angela Merkel in Berlin on Wednesday, a Reuters witness said.
Pictures from the scene showed police inspecting the estate car at the gate with the words "Stop Globalisation Politics" written in white on its right side and "You damn killers of children and old people" on the other.
There were no immediate reports of casualties and it was not clear if Ms Merkel was inside the building.
Dozens of police and a fire engine attended the incident. The driver, who appeared to be in late middle age, was taken away in a wheelchair.

"We are establishing if the driver deliberately drove against (the gate)," Berlin police said on Twitter. "He has been taken into custody."
A firefighter subsequently moved the car, which had a licence plate from the northwestern county of Lippe, away from the gate. Both the fence and car appeared largely undamaged.
Ms Merkel was scheduled to host a video conference of German state premiers on Wednesday, at which an extension to the coronavirus lockdown and further steps to combat the pandemic were due to be discussed.
