On 25 October 2025, a car driven by war criminal Veniamin Vladimirovich Mazzerin exploded in the Kemerovo Region, according to the DIU of the Ministry of Defence of Ukraine.
Lieutenant Colonel Mazzerin, born in 1980, served in the OMON special unit ‘Obereg’ of the Russian Guard in the Kemerovo Region.
‘Obereg’ is one of many Russian Guard units involved in war crimes and genocide against the Ukrainian people in the Kyiv Region.
The DIU notes that in April 2022, Ukrainian military intelligence identified the war criminals from 'Obereg' by name and planned measures aimed at bringing those on the list to justice.
