Hong Kong International airport has cancelled all departures, as anti-government protests in its main terminal continue for a fourth day.

Thousands are gathered at the airport which is one of the world's busiest.

In a statement, the airport said operations had been "seriously disrupted" by the public assembly.

Many of those protesting are critical of the actions of police, who on Sunday were caught on film firing tear gas and non-lethal ammunition at close range.

Hong Kong's mass demonstrations and unrest show no sign of abating, more than two months after they were sparked by a controversial extradition bill.
