Ukrainian National Guard troops wait as pro-Russia supporters block the Kramators-Slavyansk road on May 2, 2014. Russia warned on May 2 that Ukraine's use of the army against its own people in the east will lead to catastrophe and urged the West to renounce its "destructive policies." "As we repeatedly warned, the use of the army against one's own people is a crime and is leading Ukraine towards catastrophe," the Russian foreign ministry said in a statement.
