SYDNEY - Nine people have been injured, with one in critical condition, after a car ploughed into a crowd at a racing event in south-eastern Australia, police said.

The car was taking part in a race on the evening of Nov 15 when it flew through a fence and into a crowd of bystanders in Walcha, about 300km north of Sydney.

A 54-year-old man suffered “critical injuries”, New South Wales police said, while three others were seriously hurt.
