Mexican Navy finds 3.5 tonnes of drugs inside 'narco submarine'

A semi-submersible vessel carrying more than 3.5 tonnes of drugs was intercepted in the Pacific Ocean off the coast of Mexico, the country's navy said. The "narco sub" was roughly 85 feet long and is considered to be the largest of its kind seized by the current Mexican government, it added. Authorities believe the drug being transported is cocaine.
