UK set for cold snap as snow falls

Snow has fallen in many parts of southern England and north-eastern Scotland today.

It has forced dozens of schools to close and caused travel disruption on the roads.

Flights were also delayed while airports across the UK tried to clear their runways.

Weather forecasters warn there could be further snowfall overnight in parts of Scotland and northern England.
