Hong Kong police said protesters were guilty of "several potentially fatal attacks" targeting officers in clashes in and around the Polytechnic University over the weekend.

Chief Superintendent Kwok Ka-chuen gave a blow-by-blow account at a press conference in Hong Kong on Monday.

The first involved a police media liaison officer being struck by an arrow, which Ka-chuen described as a "murderous act".

A group of officers were rammed by a vehicle in the second incident. "To protect themselves from death or serious injury, one of the officers fired a live round at the car," he explained.

The stand-off at the Polytechnic University has seen some of the worst violence since unrest began over a now-withdrawn extradition bill earlier this year.

Several hundred protesters are thought to be trapped in the building. Besieging police forces - according to the chief superintendent's statement - have called for those inside to give up their weapons or face the threat of force.
