As reported by Censor.NET, Kovalenko spoke about transportation of explosives to Kyiv and how it was intended to be used.
"I met Konstantin four months ago. Before I left Luhansk for Kyiv on Dec. 16, Konstantin passed me a bag, which, according to him, contained something that would make 'ukrops' (derogative for Ukrainians by the separatists - ed.) uncomfortable. I took a bus. I knew what was in the bag - explosives. After I arrived to Kyiv, I went to the address (I was given - ed.).
"At 9 a.m. Konstantin called me and ordered to go to 'Nadra' bank and leave the bag near the building, where there will be lots of people. After receiving the instructions, I went to the address near the Profspilky building (at Maidan Nezalezhnosti/Independence Square - ed.). According to Konstantin's instructions, we were interested in crowded places. If there were not many people, I was supposed to go to some other crowded place. Konstantin was giving orders via telephone. If we didn't succeed, I was supposed to turn the phone off for some time.
"Whatever I did was clearly understood and comprehended by me," Kovalenko said to the camera.
