"New evidence has been found that shows the Buk missile system that was used to shoot down MH17 on the 17th of July came from Russia, and was most likely operated by Russian soldiers. Using videos posted by locals in Russia's Belgorod region back in June it has been possible to identify the Buk missile launcher seen in Ukraine on July 17th as part of a convoy of Buk missile launchers. It has also been possible to identify the Russian brigade the Buk is likely to have belonged to, and who may have operated the Buk missile launcher when it was in Ukraine."
