Tensions Continue In Eastern Ukraine Despite Diplomatic Progress

DONETSK, UKRAINE - APRIL 18: A pro-Russian activist stands guard in front of the Donetsk Regional Administration building on April 18, 2014 in Donetsk, Ukraine. The group of activists who are occupying the building have surrounded it with a barricade of tires and barbed wire and are prepared to defend it with caches of Molotov cocktails strategically placed within the barricade. 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)
