On 1 December 2016, investigators announced in Palermo the results of Operation Rose of the Winds, a multinational inquiry into hashish trafficking across the Mediterranean involving police organisations from Italy, France, Spain, Greece and Morocco with Europol support.[1][2] The operation intercepted about 30 smuggling boats, led to the arrest of more than 200 people and seized 400,000 kg of hashish.[1][2]

Police said the investigation had uncovered a new trafficking route carrying hashish from North Africa toward the Middle East, the Balkans and the rest of Europe.[2] Ben Zian Berhili, described as a king of hashish who allegedly coordinated about 400 tonnes of hashish trafficking in a year, was arrested in Casablanca in early October.[1] A Guardia di Finanza spokesperson said the operation represented a model for future international cooperation against drug trafficking.[1]
