Authorities in the southern Chinese city of Zhuhai removed wreaths, candles and bottles of Chinese alcohol, offerings laid at the scene of the deadliest mass killing in the country in a decade.

The Zhuhai attack in which a driver in southern China ploughed his car into a crowd of people and killed 35 people, severely injuring dozens more, has put the spotlight on a recent spate of similar attacks in China.

Flowers have been cleared away and mourners kept from gathering in the aftermath of China's deadliest mass murder in years.
