Ice storm in US claims 14 lives

At least 14 people have died in the US as an ice storm sweeps several states just east of the Rocky Mountains.

More than 400,000 people were left without electricity after trees and power lines toppled in the icy blast.

The National Weather Service issued ice storm warnings for parts of Missouri, Kansas, Nebraska, Iowa, Illinois and Texas and said more ice was on the way.

Ice up to 1in (2.5cm) thick layered parts of Oklahoma and Missouri, where states of emergency have been declared.

"We expect a lot more [ice], especially with another round of freezing precipitation that will be making its way through this afternoon," said a spokeswoman for Oklahoma's department of emergency.
