Kyiv Police Department says a man was shot dead outside an office building on Dehtiarivska Street in the late hours of Sunday, Oct 13.
The attackers shot the victim several times before fleeing the scene in a black motor vehicle.
The man, who ex-MP Ihor Mosiychuk claims is a member of the anti-Kremlin Caucasus Resistance movement Arslan Huseinov, later died in a hospital of the gunshot wounds sustained in the attack.
"A few hours ago, close to Kiyv center, Moscow agents shot Arslan Huseynov, who belonged to the Caucasian anti-Kremlin resistance movement. He lately resided in the Ukrainian capital," Mosiychuk wrote on Facebook late Sunday.
The police are searching for the attackers.
