Spain's Biggest-Ever Cocaine Bust: Up to 45 Tonnes Seized in Atlantic Operation

A Historic Seizure in the Atlantic

Spanish authorities have intercepted a cargo ship in the Atlantic Ocean near the Canary Islands carrying between 30,000 and 45,000 kilograms of cocaine — a seizure that could be the largest in Spanish history. The operation, led by the Guardia Civil, resulted in approximately 20 arrests.

Interior Minister Fernando Grande-Marlaska described it as "one of the biggest, not only in Spain but internationally." Spain's Civil Guard association, AUGC, called it a "historic blow to drug trafficking."

The Vessel and Its Route

The cargo ship had departed from Sierra Leone and was heading toward Libya when it was intercepted on Friday in international waters. Authorities believe the vessel was not destined for direct European ports. Instead, officials suspect the drugs were intended for mid-sea transfers onto smaller vessels for onward distribution to the European continent — a increasingly common tactic used by major trafficking networks to avoid port-based detection.

The Canary Islands as a Trafficking Chokepoint

The operation reflects Spain's intensified maritime enforcement efforts, particularly around the Canary Islands, which has become a critical transatlantic smuggling point in recent years. Trafficking operations in this corridor have grown increasingly sophisticated, involving multiple handovers at sea and the use of large commercial vessels to move industrial quantities of narcotics.

Those arrested face serious charges related to drug trafficking and organised crime. Investigations are ongoing and are targeting criminal networks across multiple continents.
