In a joint anti-drug operation code-named "Armagedon," Peruvian military and National Police troops carried out a series of raids in the remote Putumayo river valley along the Colombian border this week, arresting some 40, destroying four cocaine laboratories, and seizing large quantities of cocaine sulfate and harvested cannabis. The raids took place in the locality of Güeppí, near Laguna Pacora, Putumayo province, Loreto region. The majority of those detained were Colombian nationals, and authorities said they suspect the presence of "dissident" FARC units, who are trying to establish the zone as a staging ground to keep alive their insurgency. More than 350 troops have been deployed in the operation, with five helicopters and three planes as well as boats. The operation is being coordinated with Colombian security forces, who are carrying out similar missions on their side of the Río Putumayo. (BBC News, July 18; El Comercio, July 16)
