A fishing boat carrying 2.4 tonnes of cocaine was seized by the Mexican Navy in the Pacific in cooperation with US officials, dpa quoted authorities as saying today. The operation against the boat Charamusca took place Tuesday, but it was only made public Monday when its crew of five were brought before reporters in the port of Salina Cruz, in the southern Mexican state of Oaxaca. The Mexican Navy said the cocaine had been loaded onto the boat in Colombia and was hidden inside its fuel tanks.
