Mexican prosecutors say they will continue investigating the botched-gun smuggling probe known as Operation Fast and Furious even after a U.S. Justice Department internal watchdog report concluded that more than a dozen officials should be disciplined.

Fast and Furious allowed low-level "straw" buyers in gun-trafficking networks to leave with loads to track the guns to major traffickers. But some guns wound up at crime scenes in Mexico and the U.S.
