LONDON (AFP) - Extreme winter weather swept across western Europe on Saturday, leaving thousands of passengers stranded at London's main international airport and claiming several lives in Spain, Portugal and France, including those of three Mali-bound soldiers.

The frigid temperatures also caused delays and cancelations on major railway lines including the Eurostar train service, and transport authorities warned of further traffic disruptions with more blizzards forecast for Sunday.
