TOPSHOTS A photo taken through a shattered window shows pro-Russian protesters gathered in front of Ukrainian police officers standing guard in font of the Kharkiv regional state administration building on April 8, 2014. Ukrainian policemen were injured as a result of an operation to free the administration building from pro-Russian separatists. Ukraine's acting president said on April 8 he would treat Russian separatists who have seized buildings in the east of the country as "terrorists" who will be prosecuted with the full force of the law.
