People walk on the Puerta del Sol, a public square, in Madrid where the temperature is nearing 40 degrees Celsius, as Spain issues hot weather red alerts for three regions due to the "extreme" danger posed by scorching temperatures. Weather agency Aemet said temperatures would hit highs between 38 degrees Celsius (100 Fahrenheit) and 42 degrees across much of the drought-stricken country. The heat is expected to be even worse in the eastern regional of Catalonia, Aragon and the Balearic Islands where thermometers could reach 44 degrees Celsius. IMAGES
