Panamanian police seized a boat off the nation's Pacific coast carrying 19.4 metric tons of cocaine in one of the biggest maritime cocaine busts anywhere on record, officials said Monday. National police working with agents from the U.S. Drug Enforcement Agency seized the boat on Sunday near the island of Coiba, a police official was quoted as saying by the Associated Press. Police arrested 12 men on the boat, including Mexicans and Panamanians, and another two suspects in Panama City in connection with the drugs, the official said. The boat, which was sailing under a Panamanian flag, was being transported to Panama City on Monday, he said.
