Opposition leader Alexei Navalny accused Russian President Vladimir Putin of directing his poisoning in his first interview since the August attack.

Navalny, an anti-corruption crusader and one of Putin’s most strident critics, has been recovering in a Berlin hospital for more than a month, 24 days of which he spent in intensive care. German officials have said that he was poisoned on Aug. 20 while in Siberia with a nerve agent in the Soviet/Russian Novichok family of chemicals.
