Lightning strikes at a rock festival in Germany have left 71 people needing hospital treatment.

The Rock am Ring festival, held at a former airfield near Mendig in western Germany, about 62 miles west of Frankfurt, is one of the most popular in the country.

Performers this year include Tenacious D, the Red Hot Chili Peppers and Black Sabbath.

Germany, along with France and Belgium, has been hit by severe storms and heavy flooding in recent days.
