Russian PM strongly warns US against ramping up sanctions
Russia's prime minister sternly warned the United States on Friday against ramping up sanctions, saying that Moscow will retaliate with economic, political and unspecified "other" means.
The tough message from Prime Minister Dmitry Medvedev marked what the Kremlin sees as a red line, reflecting a growing dismay with the new US sanctions that already have sent the Russian ruble plummeting to its lowest level in two years.
