Yellow in Russia. The doctor who ran the clinic in Omsk, Siberia, where Alexei Navalny was treated immediately after being poisoned, has disappeared. The news agency Tass reported, citing a police spokesman, according to which Alexander Murakhovsky, meanwhile appointed Minister of Health of Siberia, did not return from a hunting trip he was engaged in on Friday. The 50-year-old doctor reportedly left the hunting area aboard an off-road vehicle and has not been seen since. Searches are underway with the help of drones, a helicopter and volunteers who have joined the rescue teams. On 20 August last year, the blogger and leader of the Russian opposition felt ill on a flight that took off from Omsk. The plane had returned and Navalny had been hospitalized, where Murakhovsky had spoken of a metabolic disorder, ruling out poisoning. The blogger had accused him of falsifying the diagnosis and his supporters had denounced his responsibility in the delay of the transfer to Germany, where he was then treated and where the poisoning with Novichok emerged.
