Four firefighters were killed and two others seriously injured as they battled wildfires in northeastern Spain. Sudden changes in wind direction took the authorities by surprise and revived the blaze which has raged in the Els Port park near Tarragona in Catalonia since Monday. Nearby towns are under threat, and local people are being evacuated.Carmen Chacon, the Spanish defence minister, is on the scene: “We must be very cautious and stsy alert because of the wind. Conditions are very complicated in terms of access and visibility.” A number of fires are burning across the country, although the authorities claim a blaze northeast of Madrid that led to the evacuation of some 2,000 people is now under control. Temperatures have reached 41 degrees in parts of the country though weather forecasts suggest the hot swirling winds look set to calm giving hope to Spain’s embattled fire service.
