Analysis of information sources in references of the Wikipedia article "Dmitry Bykov" in English language version.
On the domestic front, the poisoning of Pyotr Verzilov, an avant garde performance artist-turned-investigative reporter, is instructive. Two years ago, while working on an investigation into the activities of Russian billionaire Yevgeny Prigozhin and his GRU-linked mercenary group in the Central African Republic, Verzilov was poisoned with an unidentified substance in Moscow and was later treated at the same Berlin hospital as Navalny. Fortunately, Verzilov recovered, but unfortunately, the poison was never identified, making direct attribution difficult even as the culprit seems obvious. A similar story can be found in the cases of other poisoned domestic opposition figures, including Vladimir Kara-Murza and Dmitry Bykov.
