Oleg Tsarov, his collegue from the former Party of Regions and a fellow dissident Ukraine politican, wrote on his Facebook:

I BLAME THE US FOR THE DEATH OF MY FRIEND

Another one of my friends, Oleg Kalashnikov, was killed. I'm very sorry. We were friends. I knew his family. Repeatedly I tried to convince him to leave Kiev. In response, he told me that if everyone leaves, then who will fight.

I constantly tell my friends, remaining in Ukraine, that the organization of protests is futile. This power does not argue with its opponents, it eliminates them. Many of my friends were arrested, some disappeared, others were killed.

Oleg was one of the organizers of the last protest at the U.S. Embassy: people gathered and stood in silence outside the Embassy. Oleg didn't leave, did not give up. He died. He was killed.
