Honduras' Navy intercepted a semi-submersible vessel, containing between three and five tons of cocaine, in the Caribbean Sea.
The drug trafficking craft was spotted off the Mosquito Coast, close to the border with Nicaragua. The military gave chase, but the crew reportedly abandoned the semi-submersible and tried to sink it to destroy the evidence.
Five crew members were arrested, including one Honduran national and four Colombians.
Defense Minister Marlon Pascua said that the vessel is now 14 meters underwater, and divers are trying to recover the cargo and bring the semi-submersible to the surface.
According to Pascua, it is the first time the country has caught this kind of trafficking vessel.
Traffickers' increased use of submersibles and semi-submersibles to transport drugs, often from South America to Central America or Mexico, has been described by U.S. authorities as a "game changer" because they are difficult to detect.
