Spanish police say they have seized six underwater drones built to smuggle large amounts of illicit drugs remotely from Morocco.
They said the unmanned submarines – each capable of carrying 200kg (31 stone) – had more than enough range to cover the 15km (9 miles) journey across the Strait of Gibraltar.
They said trafficking gangs were supplying drugs to criminals in France, Denmark, Italy, as well as Spain.
Eight people were arrested in the police operation, in Barcelona, and in the southern provinces of Malaga and Cadiz.
