Beijing: Hurricane-force winds, freak hailstorms, pounding rain and a tornado killed 78 people in China`s eastern province of Jiangsu on Thursday and injured nearly 500 others, 200 of them critically, Xinhua reported.
The storms hit Yancheng city around 2:30 pm (0630 GMT), with witnesses saying whole villages had been levelled and huge trees felled, China`s official news agency said.
Winds of up to 125 kilometres (77 miles) per hour struck the city and outlying suburbs, destroying houses, according to the report.
"I heard the gales and ran upstairs to shut the windows," said Xie Litian, 62, from Donggou township in Funing County, told Xinhua.
"I had hardly reached the top of the stairs when I heard a boom and saw the entire wall with the windows on it torn away."
Saying that all the other houses in her neighbourhood had been destroyed, she added: "It was like the end of the world."
Photos of the scene show dazed residents near homes reduced to rubble amid tangled telephone wires, splintered wood and toppled poles.
