Several protesters have been arrested while trying to run from a Hong Kong university campus surrounded by police.

Axar.az reports citing BBC.

Around 100 people tried to leave the Polytechnic University, but were met with tear gas and rubber bullets.

In the past week, the campus has turned into a battleground as long-running anti-government protests become more violent.

A small number managed to successfully leave the campus using rope ladders before being picked up by motorcycles.

Hong Kong's Hospital Authority says 116 people have been injured and taken to hospital.

The violence is some of the worst seen during months of unrest in the semi-autonomous Chinese territory. The protests started over a controversial extradition bill, and have now evolved into broader anti-government demonstrations.

China has warned that "no-one should underestimate [its] will to safeguard its sovereignty and Hong Kong's stability", and its ambassador to the UK said the central government would not sit back and watch if the situation became "uncontrollable".
