Biggest-ever Colombian narco sub intercepted

The largest Colombian "narco sub" ever recorded -- some 30 meters long and three meters wide -- has been decommissioned in the Pacific, with three tons of cocaine found on board, the country's navy reported Friday.

The semi-submersible vessel was intercepted on its way to Central America, one of the most common routes for drug smuggling to the United States, the world's largest consumer of Colombian cocaine. The detained crew are all Colombians and claimed to have been "forced by a drug trafficking organization" to take the sub to Central America, the navy said in a statement.
