Weather stations across Spain are warning people to take extra precautions as a heat wave engulfs much of the country, increasing the risk of wildfires. The country's meteorological agency says a mass of hot air originating in Africa is moving northwards, bringing with it until at least Monday temperatures reaching 40 Celsius (104 Fahrenheit).
