Powerful Typhoon Megi slammed Taiwan and China with damaging winds, landslides and flooding rains through the middle of the week.
The storm is responsible for four deaths in Taiwan and at least two in China. One of the fatalities in China was the result of devastating landslides caused by Megi as it moved inland on Wednesday. More than 30 people were missing in the province of Zhejiang, Xinhua reported.
