MEXICO CITY (AP) — 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.

In a Friday statement, the Mexican Attorney General's Office says it's looking at the document released this week to see what it could add to its own probe.

U.S. Attorney General Eric Holder has been accused of knowing about the bungled operation, but the report cleared him and faulted mid-level and senior officials for not briefing him.

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.
