Firefighters in Spain are struggling to contain wildfires in several parts of the country, which is suffering a heatwave unusual for this time of the year.

The worst damage has been in the north-west province of Zamora where more than 61,000 acres (25,000 hectares) have been consumed, regional authorities said.
