Feb. 16 (UPI) -- El Salvador said it seized 6.6 tons of cocaine, valued at some $165 million, in the Pacific Ocean in what President Nayib Bukele described as the largest drug seizure in the country's history.

He said Sunday that the drugs were found aboard the multipurpose support vessel FMS Eagle, a 180-foot supply ship registered under the Tanzanian flag.

According to Bukele, the cargo was hidden inside the ship's ballast tanks, using a concealment method known locally as "encaletamiento." He did not disclose when the interception took place.

He wrote: "380 nautical miles southwest of our coast, the ship carrying 330 packages equivalent to 6.6 tons of cocaine in hidden compartments was intercepted," Bukele posted on social media platform X,
