Spanish police seized 4.3 tons of hashish from a privately-owned Spanish rescue ship in the Mediterranean, a spokesman said Sunday in Madrid. Fifteen suspected drug smugglers - including three crew members of the ship - were arrested, according to dpa. The ship was in private possession but was used by the rescue services. Smugglers have used this method before to bring hashish from Morocco to the Spanish holiday island of Ibiza. Those arrested were from Spain, Columbia, Romania and Morocco. -- SPA
