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.
