Snow storm strands thousands in southern US

A snow storm in the southern United States has brought several cities to a standstill, despite early warnings about expected severe weather.

Barely 3in (7.6cm) of snow caused havoc in a warm-weather region where many cities do not even have snow ploughs or fleets of salt trucks.

Airports and roads were closed as five states declared emergencies, while thousands of people were stranded on motorways, in schools and churches.
