A deadly tropical storm lashing South East Asia is turning its attention to Vietnam. At least 240 people are known to have died in the Philippines because of Typhoon Ketsana and authorities in Vietnam are bracing themselves for the worst. Some 170,000 people have been urged to leave their homes.The port city of Danang is expected to take the full brunt of Ketsana and flights there have been cancelled as the storm closes in. China has also been on Ketsana’s hit list – high winds and torrential rain battered the southern island of Hainan. The extreme conditions have caused mayhem in the western Pacific with forecasters predicting a new storm brewing near the Philippines later this week. Ketsana dumped more than a month’s worth of average rainfall in 24 hours on the capital Manila. The disaster has affected almost two million people. Hundreds of thousands have been forced to flee and many are living in make-shift shelters. The Philippines has appealed for international help to cope with the humanitarian crisis.
