Guns from U.S. sting found at Mexican crime scenes | Reuters: "At least 122 firearms from a botched U.S. undercover operation have been found at crime scenes in Mexico or intercepted en route to drug cartels there, a Republican congressional report issued on Tuesday said.

Mexican authorities found AK-47 assault rifles, powerful .50 caliber rifles and other weapons as early as November 2009 that were later linked to the U.S. sting operation to trace weapons crossing the border to Mexico, the report said.

Guns from the program, dubbed 'Operation Fast and Furious,' were also found at the scene of the murder of a U.S. Border Patrol agent in the border state of Arizona last December. It is unclear if they were the weapons responsible for his death."
