A wildfire in Spain has torn through more than 15,400 hectares of land across an 80-kilometre (50-mile) perimeter, with drone footage capturing the scale of the fast-moving blaze in the country's northern Aragon region. The regional government has declared a level two emergency, indicating the fire is threatening populated areas and critical infrastructure. The wildfire is one of several that have broken out across Spain amid a spell of high temperatures and dry conditions, which have increased the risk of rapidly spreading fires.
