On Monday August 12, thousands of pro-democracy protesters shut down Hong-Kong Airport resulting in the cancellation of almost 200 departing flights and 70 arriving flights. Numerous passengers were left stranded at the airport.
When the authorities decided to shut down the airport, the protesters feared the potential violence from the police as it had already happened in recent demonstrations. Thus, they decided to leave the airport.
Flights were also cancelled on Tuesday August 13 because of the invasion of the check-in area and the violent altercations between protestors and policemen. Today, on August 14th, most of the flights have been recovered and are operated.
