Protests in Hong Kong continue and are less predictable. Violent confrontations have taken place between police and protesters across Hong Kong, including at the Mass Transit Rail (MTR) stations and International Airport. Temporary enhanced airport access controls continue to be enforced. Further disruption to airport and other transport links is possible. Allow more time to check-in. There are media reports of enhanced screening procedures by mainland border authorities of travellers to and from Hong Kong. Be alert. Avoid large gatherings and demonstrations.
