Moscow: Russian opposition politician Alexi Navalny is in a coma and on a ventilator in an ICU in Siberia after falling ill from suspected poisoning that his allies believe is linked to his political activity.

Critica of Russia’s President Putin felt unwell on a flight back to Moscow from Tomsk, and was taken to a hospital after plane made an emergency landing in Omsk, Navalny’s spokeswomen, Kira Yarmysh said in a tweet. She added that he was in a grave but stable condition. We assure that Alexi was poisoned with something mixed into his tea. It was the only thing that he drunk in the morning. During the flight, he started sweating and asking me to talk to him so that he could focus on the sound of a voice, she said.

He then went to the bathroom and lost consciousness, and has been in a coma ever since, she said. Other opposition leaders suggested Kremlin involvement. We are sure that the only people that have the capability to target Navalny, or myself are Russian security services with definite clearance from Russia’s political leadership, pyotr Werzilov, a member of protest group Pussy Riot who ended up in ICU after suspected poisoning in 2018, said.

We believe that Putin definitely is a person who gives that goes head in this situation. Kremlin spokesmen Dmitry Peskov said it was necessary to wait for the test results showing what caused Navalny’s condition. State news agency Tass reported that police were not considering deliberate poisoning.
