Watch: Snow havoc in southeast Europe - Istanbul airport shut

Europe's busiest airport shut down in Istanbul on Monday while schools and vaccination centres closed in Athens as a rare snowstorm blanketed swathes of the eastern Mediterranean, causing blackouts and traffic havoc.
The closure of Istanbul Airport -- where the roof of one of the cargo terminals collapsed under heavy snow, causing no injuries -- grounded flights stretching from the Middle East and Africa to Europe and Asia.
Travel officials told AFP it marked the  glass-and-steel structure's first shutdown since it replaced Istanbul's old Ataturk Airport as the new hub for Turkish Airlines in 2019.
The winter's first snow created a fun atmosphere across the squares of Istanbul's ancient mosques, where children built snowmen and tourists posed for selfies.

But it proved a major headache for the 16 million residents of Turkey's largest city, where cars ploughed into each other skidding down steep, sleet-covered streets and highways turned into parking lots.
The Istanbul governor's office warned drivers they would not be able to enter the city from Thrace -- a region stretching across the European part of Turkey to its western border with Bulgaria and Greece.
