From MSN:
Russia is providing Iran with targeting information to attack American forces in the Middle East, the first indication that another major U.S. adversary is participating — even indirectly — in the war, according to three officials familiar with the intelligence.
The assistance, which has not been previously reported, signals that the rapidly expanding conflict now features one of America’s chief nuclear-armed competitors with exquisite intelligence capabilities. Since the war began Saturday, Russia has passed Iran the locations of U.S. military assets, including warships and aircraft, said the three officials, who spoke on the condition of anonymity because of the matter’s sensitivity.
