Temperatures in northern Europe have been so low that citizens of Estonia can now drive across a 20-kilometre stretch of frozen sea linking the country's two main islands.
The so-called 'ice road' connecting the islands of Saaremaa and Hiiumaa, located in western Estonia between the Baltic Sea and the Gulf of Riga, was officially opened on Sunday (8 February) with a line of cars waiting to use it that afternoon.
