Europe's arctic weather continues
Plunging overnight temperatures have triggered warnings of hazardous driving conditions for many commuters across Europe.
The Siberian weather system sweeping the continent has already been linked to 10 deaths in Romania, the UK and France.
Dubbed the 'the beast from the east', the weather front has brought with it heavy snow falls and ice which have caused major disruption to road and rail.
In mountain areas, strong winds have produced dangerous snowdrifts.
In Spain, a second cold front named Storm Emma has also brought chaos with snow alerts in at least 20 provinces.
With forecasters warning of worse weather later this week, the authorities are urging people not to undertake unnecessary travel.
If they have to make a car journey the advice is to be prepared with blankets, hot drinks and shovels and keep an eye on elderly neighbours who may find themselves unable to get out.
