In a raid on a rural drug refuge, the army arrested more than 100 alleged traffickers, seized about 1,900 pounds of pure cocaine, discovered huge coca fields and destroyed laboratories, an army official said.

The cocaine seized in Monday's operation near Colombia's northern coast was hidden among cargo bags and ready to be exported to the United States, said regional army commander Col. Carlos Castro.He said troops destroyed six cocaine-processing laboratories, arrested 103 suspected drug traffickers and found nearly 5,000 acres of coca leaf.

Soldiers also seized 30 vehicles, all with Venezuelan license plates, which had been used to transport drugs, Castro said.
