HONG KONG, Hong Kong's Airport Authority has cancelled all flights not yet checked in by Monday afternoon, as anti-government protesters peacefully demonstrated at the airport for a fourth day.

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

Traffic on roads to the airport was very congested and car park spaces were full, the authority said.
