MEXICO CITY (Reuters) - U.S. anti-narcotics agents have discovered a drug-smugglers' tunnel running under the U.S.-Mexico border and equipped with a rail track, electricity and ventilation system, the U.S. Department of Justice said.

The so-called "narco-tunnel" led from the Mexican city of Tijuana to a warehouse 300 feet from the border in San Diego, California, the department said in a statement.
