A senior Russian lawmaker said that Ukraine was informed about an aircraft carrying prisoners of war 15 minutes before it entered the Russian region where it crashed.
A Russian investigative committee on Thursday said that the plane was shot by a Ukrainian missile.
"The Ukrainian side was officially warned, and 15 minutes before the plane entered the zone they were given complete information," Andrei Kartopolov, a former general with close ties to Russia's Defense Ministry, told lawmakers.
Ukraine has denied Russia's claim that it had received information about the aircraft.
Ukrainian military intelligence spokesperson Andriy Yusov said that Kyiv had received no requests from Russia to refrain from attacks in the airspace where the plane was shot.
"No evidence has been provided for the charges ... Nothing has been shown to prove the wreckage and the presence of people on board," Yusov said on national television.
