Spain is grappling with 14 major wildfires on Friday as authorities warn of “unfavourable conditions” hindering containment efforts. The fires have already killed seven people and devastated more than 150,000 hectares (579 square miles) of land.

The fires in Spain this year have burned 158,000 hectares or 610 square miles, according to the European Union’s European Forest Fire Information System. That is an area roughly as big as metropolitan London.
