Flash floods and landslides killed at least 12 people in central Vietnam, officials said Sunday, as hundreds of troops were dispatched to clean up destroyed villages and washed out roads. Heavy rains pounded the central Khanh Hoa province over the past few days as tropical depression Toraji blew in from the South China Sea, triggering landslides that wiped out houses and destroyed a small reservoir. At least a dozen people have been killed so far while a search was ongoing for several others, an official from the provincial disaster office told AFP, refusing to be named. “We have mobilised hundreds of army troops to help people restore lives and clean up damaged roads,” he said. The main highway linking north and south Vietnam was temporarily blocked and some railway routes were interrupted, while images on state media showed destroyed houses buried under debris and vehicles submerged in floods. anicked residents told of running from their homes as landslides rumbled down nearby mountains. “We ran away after hearing the huge sound of fallen rocks… When we returned a few hours later, all our houses were destroyed,” said Nha Trang city resident Liem, quoted by Khanh Hoa province’s official online news site.Khanh Hoa — home to the popular coastal resort city of Nha Trang – was ravaged by typhoon Damrey last year, which killed 27 people. Vietnam is routinely hit by heavy rains during typhoon season from May to October.
