Heavy snow continues to disrupt travel across Europe.
It has forced the continent's biggest airports to close and stranded thousands of passengers.
Flights through London, Paris, Frankfurt, Amsterdam and Brussels have been cancelled and airports are warning of backlogs spilling late into this week.
Britain's road and railways has also been hit, with some roads made impassable after drivers abandoned their vehicles in heavy snow.
Forecasters are predicting this month could be the coldest December for a century.
