The Colombian Navy says it has intercepted the largest narco-submarine ever in the Pacific. It is a semi-submersible vessel of about 30 meters long and 3 meters wide. On board was three tons of cocaine. Three Colombian crew members have been arrested.

The semi-submersible ship was intercepted on Tuesday en route to Central America on one of the most common drug smuggling routes to the United States, the world's largest consumer of Colombian cocaine.
