Watch: Helicopters and diggers used in rescues as flooding causes chaos in Spain

Dozens people are known to have died after torrential rain caused devastating flash floods in south-eastern Spain.

Footage uploaded to social media shows floodwaters causing chaos, knocking down bridges and dragging cars through the streets.

In the town of Chiva near Valencia more than a year's worth of rain fell in just eight hours and local officials say it is "impossible" to put a final figure on the number of people who have perished.

More than 1,000 troops are being deployed to help with the rescue operation, as scores of people remain unaccounted for.
