Hyderabad: The US hasn't found any proof yet which can claim that Russian opposition leader Alexei Navalny was poisoned, media reports quoted President Donald Trump as saying.
However, he said that Washington is looking into the matter very seriously.
Navalny, a Kremlin critic and corruption investigator, fell ill on a flight to Moscow on August 20 and was taken to a hospital in the Siberian city of Omsk. He has been in an induced coma in a Berlin hospital since he was flown to Germany for treatment more than a week ago.

On Friday, NATO Secretary-General Jens Stoltenberg on Friday condemned the "appalling assassination attempt" on Russian opposition politician Alexei Navalny and called on Moscow to answer questions about the poisoning to international investigators.
German authorities have said that tests showed that he had been poisoned with a chemical nerve agent from the Novichok group. British authorities previously identified the Soviet-era Novichok as the poison used on former Russian spy Sergei Skripal and his daughter in England in 2018.
