BERLIN—Russian opposition leader Alexei Navalny, who is recovering in Germany after being poisoned in Russia, said in comments published Thursday that only Russian President Vladimir Putin could have been behind the attack against him with a Soviet-era nerve agent.
Navalny’s supporters have frequently maintained that the poisoning could have only been ordered at the top level, although the Kremlin has repeatedly dismissed the allegation. German officials have said labs found traces of a chemical agent from the Novichok family in the Russian politician’s system.
