Hijjah 25, 1431, Dec 01, 2010, SPA -- Heavy snow and subzero temperatures in western Europe closed at least four airports Wednesday, including Gatwick, one of Britain's busiest. Edinburgh airport in Scotland, Lyon-Bron airport in southeastern France, and Geneva, Switzerland's second biggest airport, were all shuttered as staff struggled to clear the runways. The European air traffic control authority Eurocontrol also reported severe delays at Berlin's Tegel airport and in northern Spain, the Associated Press reported. Swiss weather agency Meteosuisse forecast more snowfall throughout the day as a low-pressure front centered over western Europe moves slowly eastward.
