Advisers from the United Kingdom are responsible for the deaths of Ukrainian prisoners of war and crew members which were on board the downed Il-76 military transport plane in Russia's Belgorod Region, a source familiar with the matter told Sputnik on Sunday.
"The attack on Il-76 was carried out under pressure from British advisers without coordination with the air defense headquarters in Kiev and additional verification of information on the movement of aircraft over the Belgorod region," the source said.
Ukrainian intelligence knew that there were Ukrainian prisoners of war on board the Il-76 military transport plane, but nevertheless the blow was struck, according to Russian President Vladimir Putin.
The Russian Investigative Committee said that the Ukrainian armed forces used the MIM-104A guided missile of the Patriot system to shoot down the plane.
