Siberian doctors say they saved Kremlin critic Alexei Navalny`s life

Doctors at the Siberian hospital that first treated Russian opposition politician Alexei Navalny said that on Monday they had saved his life but that they had not found traces of poison in his system.

Navalny, a long-time opponent of President Vladimir Putin, fell gravely ill on Thursday after what his allies believe was a poisoning and was airlifted to Germany for treatment on Saturday.

"We saved his life with great effort and work," head doctor Alexander Murakhovsky told reporters at a news conference in the Siberian city of Omsk.

"If we had found some kind of poison that was somehow confirmed then it would have been a lot easier for us. It would have been a clear diagnosis, a clear condition and a well-known course of treatment," said Anatoly Kalinichenko, a senior doctor at the hospital.

The Russian doctors denied they had come under pressure from authorities while treating Navalny.

Navalny`s allies had accused doctors of holding up Navalny`s evacuation to Germany. The doctors initially said Navalny was not in a fit state to be transported there for treatment.

Jaka Bizilj, founder of Germany`s Cinema for Peace Foundation, told mass tabloid Bild over the weekend that Navalny, who is being treated in a German hospital, would survive.

He said: "Navalny will survive poison attack, but be incapacitated for months as a politician."
