"At least 17 people have been killed and many more injured in the United States after a powerful storm system saw tornadoes rip through Arkansas and Oklahoma.

A dozen or more twisters tore through central and southern parts of the country, decimating buildings, overturning trucks and bringing down trees and power lines.

National Guard troops have been mobilised in the worst hit areas and rescue workers have been searching debris for victims, as forecasters warned more twisters were on their way."
