Staunch Kremlin critic and opposition voice Yegor Zhukov was savagely beaten on the streets of Moscow by unidentified assailants Sunday night, the Washington Post reported.

The thugs approached and attacked Zhukov outside of his apartment in Moscow and escaped by scooter. Zhukov was sent to the hospital following the attack, but was released with no serious brain injury or internal bleeding.

“I have not suffered any property damage, but my face is broken and I feel very bad,” Zhukov said to Russian police. “I believe that the attackers attempted to cause serious harm to my health, for this purpose they inflicted multiple blows on my head, including after I fell to the ground.”
