Thousands of democratic protesters blocked roads and public transport to the Hong Kong airport on Sunday.
Thousands of flights were cancelled on Sunday, and thousands of democratic activists blocked flights to Hong Kong airports. Protesters and police fought fiercely in some of the most serious violent incidents since the start of the riots three months ago.
The airport website said that at least 16 flights were cancelled and the departure hall was crowded with backlogs of passengers who had been trying to enter the terminal.
