Russian President Dmitry Medvedev is warning that his country may respond to a US missile shield in Europe through military means. Medvedev says the deployment of an anti-missile system close to Russian borders "will of course create additional tensions." "We will have to react somehow, to react, of course, in a military way," Medvedev was quoted as saying Tuesday by the RIA-Novosti news agency. Russian officials have already warned of a military response to the US plans, but the statement by the Russian leader was likely to further aggravate already tense relations with the West. The comments come after Medvedev recognized two Georgian regions as independent nations, prompting criticism from the US and Europe.
