HONG KONG, Aug. 14 (Xinhua) -- The Hong Kong International Airport started to resume operation on Wednesday after two days of chaos and flight cancellations caused by protesters.

Passengers are now able to conduct check-in procedures after tickets or purchase vouchers are checked by airport staff. One check-in gate is left open for passengers to pass through.

Dozens of protesters are still sitting outside one of the exits of the arrival hall. A demonstration area has been marked out with security staff walking nearby.

Airport Authority Hong Kong said earlier Wednesday that it has obtained an interim injunction to restrain persons from unlawfully and willfully obstructing or interfering with the proper use of Hong Kong International Airport.

The authority emphasized that persons are also restrained from attending or participating in any demonstration or protest or public order event in the airport other than in the area designated by the airport authority.

The interim injunction expressly provides that nothing in the interim injunction shall be construed as authorizing any demonstration, protest or public order event contrary to the Public Order Ordinance.

As one of the busiest in the world, the Hong Kong International Airport handled an average of 200,000 travelers each day in 2018.
