TENERIFE, Canary Islands, Spain, Aug 17 (Reuters) - Firefighters on Thursday struggled to contain a wildfire that broke out in a mountainous national park on the Spanish island of Tenerife, prompting authorities to evacuate at least 3,800 people. "The night has been very tough...This is the most complex fire we've had in the Canary Islands in the last 40 years," the region's leader, Fernando Clavijo, told a news conference.

Last week, a heatwave in the Canary Islands left many areas bone dry, heightening the risk of wildfires. This summer, firefighters have extinguished a series of forest fires on the islands of Gran Canaria and La Palma, which form part of the Canary Islands archipelago.
