Donetsk is among the cities in eastern Ukraine where pro-Russian separatists have taken control of government offices. On May 1, some 200 people stormed the regional prosecutor's office, throwing rocks at police and raising the flag of the self-declared "Donetsk People's Republic." In this photo series, Reuters photographer Marko Djurica asked a group of pro-Russian separatists to pose for portraits inside one of the government buildings they are occupying.
