Russia's Medvedev warns of nuclear response if Ukraine hits missile launch sites

A senior ally of President Vladimir Putin warned on Thursday that any Ukrainian attacks on missile launch sites inside Russia with arms supplied by the United States and its allies would risk a nuclear response from Moscow. Former Russian President Dmitry Medvedev, now deputy chairman of Russia's Security Council, said that some Ukrainian military commanders were considering hitting missile launch sites inside Russia with Western-supplied long-range missiles. He did not name the commanders or disclose more details of the alleged plan and there was no immediate reaction from Ukraine to his threat.
