Moscow Wages War on Washington — via Twitter

The Kremlin has launched an online assault blasting the U.S. Ambassador in Moscow Michael McFaul. The spat flared up after Amb. McFaul gave a talk to students at one of Russia’s most prestigious universities. McFaul spoke frankly (he usually does) and chided the Russians on several fronts, including suggesting that they’d tried to bribe the Kyrgyz government to evict US forces from an airbase. Guardian correspondent Miriam Elder describes how Russian officials struck back, and the to and fro that followed online.
