The mission, involving 62 countries, seized more than 1,400 metric tonnes of drugs – mostly marijuana – between October 1 and November 14, according to Vice Admiral Orlando Enrique Grisales, chief of naval operations staff for the Colombian Navy.
Among the haul was 225 metric tonnes of cocaine, five tonnes of which was found aboard a semi-submersible vessel plying a marine trafficking route from Colombia to Australia, he said.
The vessel, intercepted in Pacific waters with enough fuel to reach Australia, is the third such “narco sub” intercepted on the route, Grisales told reporters.
“The first was discovered in Colombian waters, and thanks to the maps it carried, we identified the route. That’s when we began working with Australian authorities,” he added.
Australian police declined to comment on the find.
It’s not the first time “narco subs” have been seized by authorities.
Traffickers started using the vessels in the late 1990s as Colombian cartels looked for ways to evade US law enforcement patrols in the Caribbean Sea to transport their illegal cargo into the United States.
The 225-tonne seizure of cocaine is a huge haul.
