Suspected Munich car attack: What we know

Munich police said the car, a Mini Cooper, accelerated and ploughed into the back of a rally by the Verdi trade union during a strike by public sector workers. It happened in Munich's city centre at the junction of Karlstrasse and Seidlstrasseat about 10:30 local time (11:30 GMT).

Employees of day-care centres, hospitals, sanitation facilities and public swimming pools had joined the strike, calling for higher pay and longer holidays.

At the time of the collision around 1,500 people were on their way to the rally's final location a short distance away.

One shot was fired at the vehicle by police before the driver was detained at the scene.

Emergency services had been in the area because of the rally allowing the suspect to be quickly arrested and for the injured to be treated, police said.

It is unclear whether the suspect was injured.

A police spokesman told local broadcaster BR that police are checking whether there was a link between the demonstration and the incident.

The crash happened hours before the US vice president and Ukrainian president were due to arrive in the city for the Munich Security Conference - but police say they don't believe it's related.
