Fishermen discover sunken "narco-sub" in Spain after Colombian drug bust.
A homemade semi-submersible vessel, suspected to have been used for drug smuggling, was found sunk off the coast of northwestern Spain. This discovery came just days after a submarine with two dead bodies and nearly three tons of cocaine aboard was seized off the coast of Colombia. The 52-foot fiberglass vessel was discovered by fishermen who had noticed a small oil spill. Police said it was too early to say whether the vessel had been used to transport cocaine or where it came from.
