Hong Kong police on Sept. 6 stopped protesters from blocking access to the airport but fired tear gas elsewhere in the city in the 14th weekend of unrest.
Police checked for tickets and passports to only allow airline passengers into the airport, to avoid the disruption caused last weekend when protesters blocked roads leading into the airport.
For more than three months, Hong Kong has been rocked by protests initially against an extradition bill that would allow people to be transferred to the mainland for trial, but has long since evolved into wider calls for democracy.
