Hong Kong airport has suspended all the remaining flights for Monday due to the ongoing pro-democracy protest in its terminal, according to airport authorities.

Authorities said they were suspending departing and arriving flights at one of the world’s busiest travel hubs after thousands of protesters entered the arrivals halls to stage a demonstration.

“Other than the departure flights that have completed the check-in process and the arrival flights that are already heading to Hong Kong, all other flights have been cancelled for the rest of today,” the airport authority said in a statement.

“Airport operations at Hong Kong International Airport have been seriously disrupted as a result of the public assembly at the airport today,” the statement said.

It said traffic on roads to the airport was very congested and car park spaces were full. “Members of the public are advised not to come to the airport,” the statement added.

Hours later, the airport authority said all passengers were advised to leave the airport as soon as possible.
