On Tuesday, the Russian Security Service (FSB) released the results of a joint operation with U.S. troops that succeeded in dismantling an international drug smuggling network.

According to CBS News, the FSB reported the success of a multi-stage mission that seized 330 kg (727 lbs) of cocaine, estimated to be worth 1 billion rubles ($13.6 million). 

The unusual operation, which took place mainly in Moscow, was reportedly carried out thanks to the joint work of the FSB and the Drug Enforcement Administration (DEA) of the U.S. Department of Justice.

The state news agency TASS, citing an FSB statement, noted:the joint operation with the United States managed to disrupt the activities of a transnational criminal community that specialized in smuggling cocaine from South America to Russia and other European states.”

Also, a video broadcast in the Russian media revealed details of the operation. Russian agents, dressed in civilian clothes, arrested several suspects in cars and confiscated money and drugs packed in boxes.

As reported by CBS News, the mission was carried out in three stages, beginning in May in St. Petersburg, and ending with the discovery of a hideout in the Moscow region.

Several members and one of the organizers of the drug network were arrested in June while trying to sell 34 Kg. (75 lbs) of cocaine. The cocaine was seized during the arrests.

In a final part of the operation, a cache of at least 295 kg (650 lbs) of cocaine was found in the Moscow region in November, according to the Russian news agency Tass.

The statement detailed that the FSB Investigation Department will impose criminal charges against the criminal organization members in custody.

While there are doubts about bilateral relations between the United States and Russia since the Cold War and a discredited investigation into Russian interference in the 2016 election campaign raised tensions between the two countries.

In Washington, lawmakers said earlier this month that Russia was behind a recent massive cyber attack on U.S. government institutions, allegations that Russia said lacked evidence.

For now, the operation carried out by both government agencies corroborates that at least the two countries continue to cooperate on issues related to international security and organized crime.
