An explosion in the occupied village of Kalynove in Luhansk Oblast on 22 August killed Russian military personnel and destroyed ammunition, according to Ukraine's Main Intelligence Directorate.
The detonation occurred in the yard of a house where six Russian soldiers were stationed with their military transport, the intelligence agency reported.
Ukraine's military intelligence reported that in 2022, these soldiers "participated in committing war crimes in Bucha" in the Kyiv Oblast.
Bucha remained under occupation for 33 days. After liberation, Ukrainian military personnel discovered evidence of mass killings by Russian occupying forces.
The Russian unit was operating as a mobile air defense group to provide cover from aerial attacks for a Russian military repair base located near the house, according to the Main Intelligence Directorate.
The explosion destroyed two Russian pickup trucks equipped with machine guns and a UAZ "loaf" van loaded with ammunition. Three Russian troops were killed, while two more suffered severe injuries classified as "300" - military terminology for wounded requiring evacuation.
The Main Intelligence Directorate did not claim responsibility for the explosion in its statement.
The incident occurred in Kalynove village, part of the Kadiivka city community in the Alchevsk district of Luhansk Oblast, which remains under Russian occupation since 2022.
