TOPSHOTS A woman raises her fist as pro-Russians demonstrate in front of the Donetsk regional administration building, held by pro-Russian militants, on April 8, 2014. Ukraine mounted a counteroffensive on April 8 by vowing to treat the separatists as "terrorists" and making 70 arrests in a nighttime security sweep, while hundreds of militants remained holed inside the Donetsk administration building a day after proclaiming the creation of an independent "people's republic" and demanding that an independence referendum be held before May 11.
