Mexico has disbanded a select anti-narcotics unit that for a quarter of a century worked hand-in-hand with the U.S. Drug Enforcement Administration (DEA) to tackle organized crime, two sources said, in a major blow to bilateral security cooperation.
The group was one of the Sensitive Investigative Units (SIU) operating in about 15 countries which U.S. officials tout as invaluable in dismantling powerful smuggling rings and busting countless drug lords around the globe. The units are trained by the DEA but under the control of national governments.
