Russia's Medvedev warns of possible troop deployment in Ukraine, including Kyiv and Lviv.

Former Russian President Dmitry Medvedev has suggested that Moscow may send troops back to Kyiv, Ukraine, even as Russian troops struggle to progress in eastern Ukraine. Medvedev also suggested that any Ukrainian attempts to retake the occupied Crimean Peninsula would give Russia an excuse to use "absolutely any weapon." Western defense officials remain concerned by Moscow’s repeated threats to turn towards its nuclear arsenals to achieve its war aims in Ukraine.
