The Bellingcat research team investigating the crash of the Malaysian Boeing near Donetsk on July 17, 2014, named the name of a separatist with the call sign “Khmury”, who allegedly participated in the operation to transport the Buk complex from Russia.
According to Bellingcat, this man is a retired colonel of the GRU of the Ministry of Defense Sergey Nikolaevich Dubinsky. The material says that shortly after the Boeing crash in 2014, he received the rank of major general from the separatist command; he later faced extortion charges in the DPR and returned to Russia.
A man with the call sign “Khmury” appears in records of separatist talks released by the Security Service of Ukraine shortly after the plane crashed. On the recordings, he discusses the transportation of the Buk over the phone. The SBU then identified him as GRU officer Sergei Nikolaevich Petrovsky.
According to Bellingcat, Dubinsky and Petrovsky apparently both used the callsign "Khmury"; A collectors forum user identified by investigators as Dubinsky wrote on July 2, 2014 that he was "confused by some of his comrades with a man from Slovyansk who recently gave an interview and has a similar call sign."
As follows from the Bellingcat report, Dubinsky and Petrovsky are often confused in the references to “Khmuriy” in reports and publications about the Donetsk separatists.
Earlier, information that Dubinsky was involved in the crash of the Boeing appeared on Ukrainian websites . This is mentioned , in particular, on the Peacemaker website, which publishes the personal data of people whom the creators accuse of having ties with Russia.
