HEAVY snow caused traffic chaos in parts of Scotland as drivers struggled with icy roads and emergency service vehicles were stranded by deep snow.

In Edinburgh a car drove through railings and crashed nose-down into the basement area outside a building after apparently skidding on ice.

The incident happened in Saxe Coburg Street at around 6.50am yesterday.

A Police Scotland spokesman said: "A Seat Leon Cupra left the road and collided with railings before coming to a stop in a basement area of a residential property.

"No one has been injured. However, the property and vehicle were damaged."

Meanwhile, a Royal Navy Sea King helicopter was drafted in to fly a one-year-old infant to hospital after a local ambulance got stuck in wintry road conditions on the way to the family's snow-bound farmhouse near Whisgills in the Scottish Borders.

A local GP, who had been able to reach the house, provided "excellent primary care" until the Sea King arrived, the Royal Navy said.

The child, who was described as "unresponsive" at the scene, was airlifted to hospital in Carlisle along with his mother, by which time his condition was said to have improved.

It came as more than 130 schools across Scotland were forced to close with the Highlands and Dumfries and Galloway worst affected - leaving youngsters free to enjoy sledging.

Nine inches of snow fell at Tulloch Bridge in Inverness-shire, the deepest accumulation in Scotland, with three inches also falling in Aviemore.

The Met Office has now downgraded its weather alert from amber to yellow, with a continued risk from snow and ice across the whole of Scotland today. The northern half of Scotland is also covered by a yellow alert for snow and ice until at least Monday, while the Central Belt, Borders and Dumfries and Galloway are expected to experience a return to milder conditions.
