Narco-sub carrying 1.7 tonnes of cocaine seized in Atlantic

Portuguese authorities detain four after seizing narco-sub with 1.7 tons of cocaine in Atlantic. The vessel, headed for Iberian Peninsula, was captured 1,000 nautical miles off Lisbon in a joint operation by police and navy. Following the arrests of South American crew members, the sub, too fragile to tow, sank at sea, marking the latest in a series of similar recent drug interceptions in the area.
