The Berlin hospital treating the seriously ill Russian opposition leader, Alexei Navalny, has said he appears to have been poisoned.
The Charité hospital released a statement saying “clinical evidence suggests an intoxication through a substance belonging to the group of cholinesterase inhibitors”.
Navalny fell ill on an internal flight in Russia last week, doctors who treated him in Russia say the substance mentioned by the hospital is not present.
His flight made an emergency landing in Omsk where he was first treated.
In the meantime, his supporters are suspecting that Navalny was poisoned in a cup of tea he drank at the airport in Tomsk.
In their latest statement released after that of the German medical team, the Omsk doctors say tests showed no sign of cholinesterase inhibitors in his body, suggesting that his illness was caused by a metabolic disorder triggered by low blood sugar.
