MOSCOW (Reuters) - Russia expressed outrage on Friday over a "frenzied anti-Russian campaign" by U.S. media and political analysts, stepping up a war of words that has intensified during the Ukraine crisis.

Ties between Moscow and Washington have sunk to their lowest level since the Cold War over the crisis in Ukraine, and each side has accused the other of waging an information war.
