DONETSK, UKRAINE - APRIL 18: A pro-Russian activist stands guard inside the Donetsk city government building on April 18, 2014 in Donetsk, Ukraine. Nearby, activists have also taken over the Donetsk Regional Administration building. Activist leader, Denis Pushilin, who is co-head of the self-declared Donetsk People's Republic, said today that they will not surrender until there is a change of leadership in Ukraine. Several bands of separatists, similar to those in Donetsk, have been occupying government buildings in other eastern Ukraine cities in recent weeks. (Photo by Scott Olson/Getty Images)
