Smoke from a huge wildfire in central Portugal enveloped skyscrapers known as the "Four Towers" in Madrid 400 km (250 miles) away on Tuesday, and residents of the Spanish capital complained of a strong burning smell.
The fire, which has ravaged Portugal's Serra da Estrela national park, started on Aug. 6 and had been largely put out as of Sunday, but reignited again on Monday, leading to the evacuation of several villages.
