Hong Kong International Airport cancelled all departures on Monday, as thousands of anti-government protesters occupied and caused disruption, BBC reports.
Hong Kong airport cancels all flights over protests
STEPANAKERT, AUGUST 12, ARTSAKHPRESS: Passengers have been told not to travel to the airport, which is one of the world's busiest transport hubs.
In a statement, officials blamed "seriously disrupted" operations.
Many of those protesting are critical of the actions of police, who on Sunday were filmed firing tear gas and non-lethal ammunition at close range.
Some protesters wore bandages over their eyes in response to images of a woman bleeding heavily from her eye on Sunday, having reportedly been shot by a police projectile.
In a statement on Monday afternoon, Hong Kong's Airport Authority said they were cancelling all flights that were not yet checked in.
More than 160 flights scheduled to leave after 18:00 local time (10:00 GMT) will now not depart.
Officials said arrivals already heading into Hong Kong would still be allowed to land, but other scheduled flights have been cancelled.
On Sunday afternoon, a peaceful rally in the city's Victoria Park led to clashes when protesters moved out of the area and marched along a major road despite a police ban.
There were confrontations in several central districts and police used non-lethal bullets in an attempt to disperse the demonstrators.
A number of people, including a police officer, were injured in the clashes.
