Schools closed across the UK as more
snow blanketed the country, with what was thought to be the deepest "extreme freeze" for a decade.
About 70 schools shut to the children of key workers and vulnerable pupils in
County Durham, as many did in Essex, Suffolk and Derbyshire.
Roads as far south as Kent became impassable because of a thick sheet of ice, and the M20 - the main route across the county - was closed in both directions on Wednesday following a crash.
Forecasters warned that further travel disruption was likely, with roads too treacherous to use, and cancelled rail services.
National severe weather warnings for snow and ice have been issued for much of the UK for the rest of this week.Met Office chief meteorologist Dan Suri said: "Weather for the rest of this week will continue to be very cold, with daytime temperatures only reaching a degree or so above freezing at best for many, and strong easterly winds continuing to make it feel even colder."
