Dubinsky is also known as a fighter of the "armed forces" of the so-called "Donetsk People's Republic" ("DPR") whose nom de guerre is "Khmuryi" ('Gloomy' or 'Grumpy'), Bellingcat said in a new report.

According to experts, the relocation of the Buk was arranged by personnel of the 69th separate logistics brigade of the Russian Armed Forces. Such conclusions were made by Bellingcat experts after they had examined images from social networks that were taken in Rostov region amid the transportation of the missile system.
