Hundreds of people in Croatia have spent the night in their cars or at petrol stations and reception centres after a snowstorm halted traffic and cut off parts of the country.

The sudden change in the weather over the weekend after a period of warm and balmy days has also snarled up traffic in neighbouring Serbia and Bosnia, leaving areas in western Serbia without power and cutting railway traffic to neighbouring Montenegro.
