Russia's Investigative Committee has offered further insight into the killing of pro-Russian Ukrainian leader and head of Oplot Yevgeny Zilin in Moscow on Monday, suggesting that his business dealings in coal in the Donbass as the most liking motive behind his murder. This hypothesis has been confirmed by the testimony of Andrei Kozyrev, who was with Zhilin, bore witness to the latter's murder, and was badly injured himself.
