Record heat warning as forest fires rage in Spain and Portugal

Temperatures are expected to hit 44 degrees Centigrade in Spain and Portugal on Wednesday as the two countries boil under their third heatwave of the summer.

With huge forest fires raging across southern Portugal for the fifth successive day, Spain's weather service warned that the average temperature across the country could hit a 70-year record.

Winds and extreme heat are also driving fires that have devastated 15,000 hectares of trees in neighboring Portugal over the past few days. Experts say the recurring heatwaves, which have been getting longer and more intense, are a consequence of climate change.
