Last night our CBS News investigation reported on ATF's Project Gunrunner and allegations that it included a secret operation near the border that intentionally allowed thousands of assault rifles and other weapons to hit the streets.

Sources told us many of the weapons ended up in the hands of Mexico's drug cartels. Two AK-47 type assault rifles turned up at the murder of border patrol agent Brian Terry on December 14th. Sources also told us that ATF agents operating in Mexico were instructed not to alert Mexican authorities about the operation.

The Mexican government responded today. Ricardo Alday, spokesman for the Mexican Embassy in Washington, D.C. said Mexico intends to continue to work with the U.S. to enhance intelligence and information sharing, and that Mexico "will continue to encourage more aggressive interdiction efforts on the U.S. side of the border."
