Head of the Anti-Corruption Foundation Alexei Navalny is breathing through a ventilator, and his condition is critical but stable. This is what Deputy General Doctor of Emergency Hospital #1 of Omsk Anatoly Kalinichenko told reporters, reports RIA Novosti.

As reported earlier, the plane carrying Navalny made an emergency landing in Omsk, after which Navalny started feeling bad and was hospitalized.

It was also reported that before the flight from Tomsk, Navlany had only drunk black tea at the airport’s café. It is assumed that the opposition figure was poisoned, as reported the Foundation’s spokesperson Kira Yarmish.

The airport is ready to provide the video recordings, and police have conducted inspections.

The Foundation’s lawyers plan to address the Investigative Committee.

Navalny’s doctor Anastasia Vasileva has left for Omsk.
