CIUDAD JUAREZ, MEXICO (AP) -- The Associated Press reports Mexico's most powerful kingpin now controls coveted drug trafficking routes through Ciudad Juarez.
The two-year battle has left more than 5,000 people dead. Violence-plagued Juarez is across the border from El Paso, Texas.
AP reports the conclusion by U.S. intelligence adds to evidence that Joaquin "El Chapo" Guzman's Sinaloa cartel is winning Mexico's drug war.
The assessment is based, in part, on information from confidential informants with ties to Mexican drug gangs.
Details are from a U.S. agent who sometimes works undercover.
Also, FBI spokeswoman Andrea Simmons in El Paso confirms that the majority of drug loads arriving from Juarez now belong to Guzman.
Mexican Federal Police Chief Facundo Rosas says while authorities work to confirm the U.S. assessment, "These are valid theories."
