Kremlin critic Alexei Navalny told a German magazine that Russian President Vladimir Putin was behind his suspected poisoning and stressed that he was not afraid.
Navalny was flown from Russia to Berlin in August after falling ill on a domestic flight. He received treatment in the Charite hospital for what Germany said was poisoning by a potentially deadly nerve agent before being discharged in September.
"I claim that Putin is behind the crime and I don't have any other versions of what happened," Navalny told Der Spiegel, according to an extract of an interview due to be published later on Thursday.
