The Venezuelan army completed drug-fighting Operation Sierra after sweeping a training camp attributed to the Colombia's United Defense (AUC).

"We think that it belongs to the AUC because their patches were there," said General Jesús González, the commander of the army's Special Strategic Taskforce.

The military gave the news near the presumably paramilitary camp located in the Perijá mountains, on the Venezuelan-Colombian border, western Zulia state, Efe reported.

"We think they are (AUC), but cannot have final evidence." The only "evidence," he added, are the insignias or bracelets found. "But we could not detain anybody."

The camp was found some days ago by a "surveillance patrol within the framework of Operation Sierra." It is located less than 500 meters from the Venezuelan-Colombian border, at Catatumbo municipality.
