A British man and woman have died in a dune buggy accident on the Greek island of Santorini, fire authorities say.

The pair, aged in their 20s, fell into a 200m (650ft) ravine while driving on the Profitis Ilias mountain on Sunday afternoon, according to local media.

The Greek fire service said eight firefighters in two vehicles attended the scene at 14:27 local time.

The Foreign Office said it was assisting their families and was in contact with the Greek authorities.

The accident took place on the highest point of the island in the south of the Aegean Sea, a popular holiday destination for British tourists.
