German hospital: Clinical findings point to Navalny's poisoning

Tests on the Russian opposition politician show evidence of poisoning but his life not in danger, Berlin hospital says.

The German hospital treating Russian opposition politician Alexey Navalny has said tests indicate that he was poisoned.

The Charite hospital said in a statement on Monday that the team of doctors who have been examining Navalny since he was admitted on Saturday have found the presence of "cholinesterase inhibitors" in his system.

They said at the moment the specific substance is not yet known.

The hospital said "the patient is in an intensive care unit and is still in an induced coma. His health is serious but there is currently no acute danger to his life."

The 44-year-old was brought to the German capital Berlin on Saturday from Siberia, where he fell ill on a flight with what Russian doctors have blamed on a metabolic disorder.

The Kremlin critic, Russia's best-known opposition figure, was rushed into intensive care on Thursday after his plane made an emergency landing in the Siberian city of Omsk.
