At least 35 people have been killed in a car attack in southern China, believed to be the deadliest known act of public violence in the country in decades.

Police say a man crashed his car into a stadium in Zhuhai on Monday where he ran down groups of people exercising on the sports track.

At least 45 people – among them elderly and children – were reportedly injured.

While reporting about the attack, BBC China correspondent Stephen McDonell was angrily ordered to stop filming.

It is not clear who the man who tried to stop the reporting was, though when sensitive stories like this unfold in China, local Communist Party officials organise groups of cadres to pretend to be outraged locals who have been given the role of targeting foreign reporters so as to prevent any coverage.
