Thousands gather in Sydney calling for end to violence in China's Hong Kong

Radical protesters in Hong Kong have abandoned their peaceful protests and unfortunately some of them have turned into violent mobs who smashed the parliament, ransacked the police stations and threw bricks and petrol bombs on the streets, Tony Jiang said.

"We support and we understand peaceful protest, but we believe it has grown into an out-of-control situation."

Horrified by the current unrest in the global financial hub, a female marketing student from China who was too afraid to give her full name said she had become very concerned for her friends living in Hong Kong.
