In the Pacific Ocean, 2 submarines with dead bodies and 3 tons of cocaine were seized off the coast of Colombia.

A submarine carrying two bodies and nearly three tons of cocaine has been seized in the Pacific Ocean off the coast of Colombia, the country’s navy said Sunday. Two survivors “in poor health” and first aid were also found on the ship.

“The poor health of these people is believed to be due to the infiltration of toxic fumes caused by fuel problems inside the boat,” said Capt. Cristian Andres Guzman Echeverri. video released by the Navy.

The nearly 50-foot-long submarine was carrying nearly 5,800 pounds of cocaine, worth more than $87 million, officials said. The Navy said the ship was bound for Central American countries and that the seizure kept more than 6 million doses of cocaine from the illegal market.

The surviving men, the two victims and the seized drugs were brought to Tumaco, “where they were presented to the Technical Intelligence Corps of the Attorney General’s Office,” the statement said.

Officials posted images the seizure of the submarine, showing officers carrying packages from the ship. One video shows officers carrying a victim on a stretcher to an ambulance.

“The Colombian Navy will continue to use all its capabilities to stop drug trafficking,” Echeverri said.

Traffickers in the region commonly use so-called “narco subs” to transport drugs. Last year, the Colombian Navy seized a semi-submersible vessel worth about $150 million that was carrying 4 tons of cocaine.

Submarines sometimes reach North America. In 2019A submarine carrying 12,000 pounds of cocaine worth more than $165 million was seized by the US Coast Guard.
