OTTAWA — The federal government has issued a travel advisory that urges Canadians travelling to Hong Kong to exercise “a high degree of caution” because of the escalating ******** in the city.

The government’s website says there are “identifiable safety and security concerns or the safety and security situation could change with little notice.”

Canadians are advised to “exercise a high degree of caution at all times, monitor local media and follow the instructions of local authorities.”

The United States, Australia, Ireland, ******* and Japan are among several other nations that have also issued travel advisories to their citizens.

Pro-democracy protesters demonstrated at Hong Kong’s airport Friday even as the city sought to reassure visitors of their welcome despite the increasing levels of ******** surrounding the two-month-old ******* movement.

The government concedes road blockages and confrontations between ****** and protesters have caused inconveniences, but says they were limited to specific areas.

The ********, however, are not abating, and more are planned for this weekend, including at the airport, where protesters holding signs staged a sit-in at the arrival and departure halls Friday.
