Honduran and US authorities have seized at least 4.6 tons of cocaine on a boat in the Caribbean Sea and arrested six of the vessel's crew members. Honduran Navy Comm. Juan Pablo Rodriguez says the cocaine was found on the Honduran-flagged "Eclipse" about 160 kms off the Honduran coast in a joint operation with the US Coast Guard. The area is near the Nicaraguan border. Rodriguez said Saturday that the officials were still searching the boat and the total of the haul could end up being more than 4.6 tons. Honduran authorities estimate that 100 tons of cocaine from Colombia pass through the Central American nation each year en route to the United States.
