Huge chunks of space rock crashed to earth after a meteor exploded in the skies over Russia, with the power of an atomic bomb.
It was travelling so fast it created a sonic boom that shattered thousands of windows which, in turn, injured more than seven hundred people around the Russian city of Chelyabinsk.
ITV News correspondent Paul Davies reports:
Where did it come from? What was it made of? What can be done if we know a meteor or asteroid is going to hit Earth?
A look at some of the best video from the Russian Meteor. More than 400 people were injured after it flew over a Russian city.
