The ongoing sit-in protest at Hong Kong International Airport has forced dozens of flights to be canceled on Wednesday.
Most of the demonstrators left the airport on Wednesday morning and boarding procedures resumed. But about 100 arriving and departing flights have been canceled.
Boarding was suspended on Tuesday when the protesters occupied the departure hall, blocking the entrances to the security checkpoint.
The demonstrators beat a man who had an ID card from mainland China. They also poured water over his head, claiming he was an undercover police officer.
The incident triggered a clash around the entrance of the airport. The police used tear gas against the protesters.
The demonstrators' demands include the complete withdrawal of an extradition bill that would allow suspects to be sent to mainland China.
They are holding protests at the airport to get publicity for their demands. It is difficult for the police to use force to remove them as the airport is used by many foreign travelers. The demonstrators are warning that they will put further pressure on the Hong Kong government.
