MOSCOW  — Russia’s prime minister sternly warned the United States against ramping up sanctions, saying Friday that Moscow would 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 growing dismay with announced U.S. sanctions that have sent the Russian ruble plummeting to its lowest level in two years.
