A number of tornadoes have hit parts of Wales and the Midlands felling trees and overturning caravans.

Forecasters have said any further tornados will be confined to northern parts of the Midlands.

Thomas Scarrott, director of the Clarach Bay Holiday Village, near Aberystwyth told WalesOnline 15 to 20 caravans were upturned and overturned.
Mr Scarrott said: "It was a very frightening experience, it just came out of nowhere.
"It must have been a tornado because a holiday village opposite us doesn't seem to have any damage.
"Thankfully we are closed so there is only a few workers and maintenance people, otherwise I reckon there would have been a lot more injuries."
The Mid West Fire Service attended the scene at the caravan park where they isolated several gas cylinders and told reporters the site had been evacuated.
