 Irish Rangers made the country's biggest ever drug seizure after a naval operation involving warning shots being fired at a Panamanian cargo vessel which had refused to follow instructions, authorities said on September 27.The seizure of 2,253 kilograms of cocaine worth an estimated 157 million euros, $166 million, came after members of the Army Ranger Wing boarded the vessel off the country's southeast coast using ropes dropped from a helicopter in high winds, the vessel was registered in Panama and originated in South America and the product was supplied by one of the murderous South American cartels behind cocaine shipments to Europe, said Justin Kelly, assistant police commissioner for organized crime.
