Russian opposition leader Alexei Navalny has accepted a duel challenge issued by the head of the National Guard troops days after his release from prison.

National Guard director Viktor Zolotov, a former presidential bodyguard, promised to pound Navalny into a “juicy steak” last month as punishment for the Kremlin critic’s videos exposing alleged corruption by Russia’s top government officials, including Zolotov himself. Navalny was serving a month-long sentence for violating protest rules at the time of the challenge and was only released Sunday after 20 more days in jail on new protest charges.
