LONDON: The car carrying British Prime Minister Boris Johnson was crashed into from behind in central London on Wednesday after taking evasive action when a pro-Kurdish demonstrator ran on to the road.

The protester was stopped and detained, according to an AFP journalist on the scene, after he ran towards Johnson's Jaguar as it was leaving under police escort from the Houses of Parliament.

A video posted online showed the car braking before being struck by the following vehicle in the convoy, causing a large dent, while police wrestled the protester to the ground.

Johnson's Downing Street office confirmed it was the prime minister's car and there were no reported injuries.-AFP
