Doctors at the Siberian hospital that first treated Russian opposition politician Alexei Navalny said on Monday that 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.
