Smoke billows over Madeira as a wildfire rages around the Pico do Areeiro mountain on the Portuguese island. Around 150 firefighters have been battling the blaze on two main fronts, as the fire, which started in the Ribeira Brava district, spread to the nearby Camara de Lobos and Ponta do Sol districts in the southern part of the island. At Portugal's request, the EU also activated its Copernicus satellite system to help monitor the blaze, which has raged for a week and threatens a UNESCO-listed forest. IMAGES
