Spanish firefighters on Sunday battled a new front of fires near the coastal city of Valencia, where at least 15,000 people were evacuated.

Spain has already evacuated tens of thousands of people from villages west of the capital Madrid where extremely dry conditions have been worsened by heatwaves and strong winds.

In the Valencia region, on Spain's eastern coast, authorities said they were struggling to contain fires.

"The fire is beyond our capacity to extinguish; it has a perimeter of about 21 kilometers (13 miles). It is still difficult to determine the number of hectares burned," Juanfran Perez Llorca, Valencia regional president told reporters late Saturday.

"We have evacuated around 15,000 people."
