Australian university students have been urged to leave Hong Kong as militant students clash with police during major protests in the city.

The Umbrella Movement that has brought Hong Kong to a standstill is in its fifth month and shows no sign of slowing down.

In fact, violence is escalating as protesters have turned the campus of Hong Kong’s Chinese University into a fortress stockpiled with petrol bombs and bows and arrows.

The University of Sydney has started contacting students urging them to come home after classes were suspended for the last few weeks of the semester.
