Russian intelligence sees U.S. military buildup on Iran border

Russian military intelligence services are reporting a flurry of activity by U.S. Armed Forces near Iran's borders, a high-ranking security source said Tuesday.

"The latest military intelligence data point to heightened U.S. military preparations for both an air and ground operation against Iran," the official said, adding that the Pentagon has probably not yet made a final decision as to when an attack will be launched.
