Police in Spain said Wednesday they had seized 4.2 tonnes of hashish in the south of the country and arrested nine suspected drug traffickers. The drugs were found in April on two speedboats, one carrying 2.4 tonnes of hashish and the other 1.8 tonnes, police said in a statement. Police also seized 1.2 million euros (1.9 million US dollars), four vehicles as well as several guns and documents during 18 searches carried out as part of their probe of the group which is suspected of smuggling hashish from Morocco. They did not give an estimated street value for the drugs. Morocco is believed to be one of the world's largest producers of hashish. It has vowed to crack down on trafficking and toughened border controls in recent years. Spain, with its extensive coastline, is Europe's main entry point for Moroccan hashish and cocaine from South America, mostly from its former colony Colombia, the world's top producer of the drug.
