Russia is increasingly concerned about security from the sky: air defense systems have been installed on rooftops in Moscow's government quarter. Systems have also appeared in several other places in Russia, including near Vladimir Putin's lakeside home in Valdai. What is the Kremlin really worried about?
More air defense systems were installed at several other sites in or near Moscow, including Odintsovo district, about six miles from President Vladimir Putin's residence at Novo-Ogaryovo.
