Spanish police say they have broken up a gang specialising in night-time helicopter flights to import the drug hashish from Morocco.
The Guardia Civil said they had seized two helicopters and almost 800kg (125st) of hashish, derived from the cannabis plant, in a joint operation with Moroccan police.
They also arrested nine people, two of whom they said had expertise with night flying.
The operation, which took place in January, involved a raid on a ranch near the Spanish city of Cadiz after investigators observed a helicopter making a brief trip to Morocco and back.
Police said one gang leader had died in a car crash when he attempted to flee the scene.
