Navy officials in Colombia say they have seized 5.2 tons of cocaine on a ship off the country's Pacific Coast.

A navy statement issued Tuesday calls it the largest cocaine seizure in Colombia's Pacific region in the past two years and says U.S. Drug Enforcement Administration agents participated in the operation.

The statement says the boat was seized 190 miles (305 kilometers) from the southern port of Tumaco in Narino province. The merchant ship's 14 crew members were arrested.

So far this year, Colombia's navy says it has seized 22.8 tons of cocaine.
