Vietnam has ordered more than half a million people to evacuate as Typhoon Kajiki barrels towards the country with gales as strong as 100 miles per hour.

Vietnam announced plans to evacuate more than half a million people and ordered boats to stay ashore, while the southern Chinese city of Sanya closed businesses and public transport on Sunday as both braced for an intensifying Typhoon Kajiki.

Vietnam has shut down airports, closed schools, and begun mass evacuations as it prepares for the most powerful storm so far this year.
