Spanish authorities have arrested 13 crew on a Comoros-flagged cargoship after finding hashish on board.
Tax officials and police carried out the raid on the 4,200-dwt Lady Boss (built 1982) off Almeria on Tuesday, local media said.
They found 18 tonnes of the drug in 600 bales.
Of the arrested men, 11 were Ukrainian and two were Bulgarian.
The vessel had been observed for a week.
