Kerry Says Russia's 'Window To Change Course Is Closing'

(Washington, DC) -- Secretary of State John Kerry says the window for Russia to change course is closing. Kerry delivered the stern warning today saying if Moscow continues its military actions along the Ukrainian border it will not only be a grave mistake, it will be an expensive mistake. Earlier Thursday Russia stepped up military exercises along the border with Ukraine. This was in response to Ukrainian forces killing up to five pro-Russian separatists in clashes at three military checkpoints.
