Igor Kolomoisky, billionaire and governor of the Dnipropetrovsk region speaks during an interview in Dnipropetrovsk May 24, 2014. Ukrainian self-defense fighters who clashed with armed pro-Russian separatists on Friday are at the forefront of Kiev's efforts to prevent the country splitting. Co-funded by Kolomoisky, one of Ukraine's richest men, they play a more assertive role than the unarmed miners and metalworkers working for another oligarch, Rinat Akhmetov, who more recently spoke against the rebels.
