Cartagena, Colombia, October 2, 2007—Police officers inspect packages of cocaine labeled with British flags, that were seized by the Colombian navy.

Two tons of the drug, most of it destined for the United States, was confiscated from a truck on the country's Caribbean coast.

The British flag is used as an arbitrary marker for tracking shipments, an official pointed out. "It is the logo that is attached to each shipment to show in which cocaine laboratory the drugs were produced," Admiral Roberto Garcia, the navy commander of the Caribbean coast, told the Associated Press.
