Gates: US has evidence of Iranian action in Iraq

Serial numbers and markings on explosives used in Iraq provide "pretty good" evidence that Iranians are providing either weapons or technology for militants there, US Defense Secretary Robert Gates asserted Friday. Offering some of the first public details of evidence the military has collected, Gates said, "I think there's some serial numbers, there may be some markings on some of the projectile fragments that we found," that point to Iran. At the same time, however, he said he was somewhat surprised that recent raids by coalition and Iraqi forces in Iraq swept up some Iranians. Speaking to reporters at a defense ministers' conference here, Gates said Friday, "I don't think there was surprise that the Iranians were actually involved, I think there was surprise we actually picked up some."
