July 16 (Reuters) - At least 4,000 people have been evacuated as a forest fire burned out of control on the Spanish island of La Palma, authorities said on Sunday, as Europe struggled to cope with a heatwave.

The fire in La Palma started in the early hours of Saturday in El Pinar de Puntagorda, a wooded area in the north of the island in the Canaries. The blaze forced the evacuation of people from the villages of Puntagorda and neighbouring Tijarafe.
