Outspoken Kremlin critic Aleksei Navalny, who is currently in Germany after surviving a poison attack, has tweeted that he plans to return to Russia on January 17.

Navalny was flown to Berlin for emergency medical care after being poisoned in Russia in August.

Laboratory tests conducted in Germany, France, and Sweden have established that Navalny was poisoned with a toxin from the Russian-made Novichok group of Soviet-era nerve agents, a conclusion confirmed by the International Organization for the Prohibition of Chemical Weapons.

Navalny has accused Russian President Vladimir Putin of ordering the poisoning, an allegation rejected by the Kremlin.
