CANBERRA, June 23 (Xinhua) -- Thick fog blanketing Australia's largest city of Sydney has caused all flights to be grounded at Sydney Airport on Friday morning, according to an airport spokesman.

    Although the airport is not closed, no flights are landing or departing from the airport.

    International and domestic flights would be assessed on a case by case basis until visibility improved, Australian Associated Press quoted the spokesman as saying.

    Five international flights, mostly from the United States, have been diverted to Brisbane, capital of Queensland state.

    The spokesman said passengers should contact their airlines to confirm departure times. Enditem
