Snow and ice disrupt travel as cold spell continues
Snow and freezing temperatures are causing major problems for road, rail and air services in much of the UK, and thousands of schools are shut.
There are icy road warnings, and up to 15cm of snow could fall in some areas.
Many roads are gridlocked, some trains and buses have been cancelled, and Gatwick and Edinburgh airports will be closed until at least Thursday morning.
