Colombia

Police in Bogota's El Dorado airport were tipped off when a drug-sniffing dog detected the narcotics hidden in 48 boxes of a 1-metric ton cargo shipment bound for a company in the Mexican state of Sinaloa. Authorities alerted their Mexican counterparts, who then found a similar amount sent a few hours earlier on a flight to Mexico City.

Colombia is the largest supplier of cocaine to the U.S. and much of the narcotic lands on American streets through Mexican drug cartels.

Maduro said during a visit to Vietnam that the conspiracy has the consent of Colombia's government. He didn't present any evidence to back the claim but said he would soon.

Maduro and his Colombian counterpart Juan Manuel Santos have been trading barbs ever since last week's expulsion of more than 1,000 Colombians living illegally in Venezuela. Maduro accuses the migrants of being behind a wave of crime and smuggling along the border.

Even as the diplomats met in this Caribbean coastal resort, motorists in the Colombian city of Cucuta complained of long gas lines as Venezuela's security offensive cuts off trade, legal and otherwise, between the two nations.

Across the border, scores of Colombians packed their belongings into suitcases and prepared for an army escort out of Venezuela, joining the estimated 1,000 of their compatriots who have already been deported.
