Security Services of Ukraine chief Valentyn Nalivaichenko, at a late night news conference, said the government is making all evidence in the investigation public, including intercepted phone calls between two members of the Russian military special services unit – known as the GRU – in which they discussed shooting down the airplane.
However, Russian President Vladimir Putin denied any involvement, saying Ukraine is responsible.
However, Ukrainian officials say the Kremlin-backed separatists evidently mistook the commercial aircraft for a Ukrainian military one in an area of fighting between the government and Russian-supported forces.
In the conversation, Nalivaichenko says that one Russian officer “who is a terrorist bastard” calls another, identified as Russian Col. Vasily Geranin, to report that subordinates who arrived on the crash scene discovered that it was a civilian airliner downed with lots of casualties. Other news reports from the scene in a field in Donetsk Oblast, near the city of Torez, suggest that Kremlin-backed separatists have seized the airline’s flight recorder, crucial to any investigation, and are taking it to Moscow.
