HANOI: Extreme weather caused by Typhoon Rammasun has killed 27 people in Vietnam, with the storm unleashing flash floods, landslides and lightning strikes, authorities said on Tuesday. Heavy rain flooded 7,200 houses and 4,200 hectares (10,300 acres) of cropland, with the north of the country worst hit, the national flood and storm control committee said. The cost of the damage was estimated at around $6 million. Rammasun—meaning “Thunder God” in Thai—had earlier barrelled through the Philippines and then hit southern China, killing more than 100 people and wrecking over 111,000 homes. It was the most powerful storm to strike China’s southern areas since 1973, the country’s National Meteorological Center said, and brought torrential rains.
