Powerful tornadoes have swept through the US Midwest, destroying buildings and overturning vehicles in the states of Illinois, Indiana and Kentucky. At least five people were killed and it is feared that several hundred people may have been injured in the fast-moving storms, according to the (BBC). A number of people are said to be trapped inside buildings. Forecasters say up to 53 million people could be affected. Hailstones the size of tennis balls have been reported. The rapid-moving storm - with winds of up to 111km/h about (68mph) - is continuing its way east. November is ordinarily one of the quietest months in the tornado calendar, meaning these storms are unusually destructive for this time of year. All the fatalities were reported in Illinois, which was the hardest hit state. Illinois officials are describing the situation as "dangerous and volatile".
