Wildfires drove thousands of people from their homes near a rare nature reserve in Spain's Canary Islands Monday after a separate mainland blaze killed two, authorities said. Firefighters struggled to control the flames that engulfed the wooded hillsides on the island of La Gomera, reducing lush green trees to black dust, spewing grey smoke and displacing residents and tourists. That fire started more than a week ago and has devastated more than 4,100 hectares of land, including hundreds of hectares in the Garajonay National Park, a UNESCO World Heritage site that is home to rare subtropical plants.
