MOSCOW (Reuters) – Doctors at the Siberian hospital that first treated Russian opposition politician Alexei Navalny said on Monday they had saved his life.

Navalny, a long-time opponent of Russian President Vladimir Putin and campaigner against corruption, fell gravely ill on Thursday after what his allies believe was a poisoning and after two days at the Siberian hospital was flown for treatment in Germany.
