International Tribunal on MH17 has just published clear evidences that Russian forces have massively shelled Ukrainian territory from firing positions located in Russia.
During summer 2014, Ukrainian officials and also the U.S. government were already publicly stating that the Russian military were active in the war. A number of subsequent reports have corroborated these claims, documenting the presence and death of Russian servicemen in eastern Ukraine, as well as the existence of Russian military equipment inside Ukraine.
It should be mentioned that EU and other countries talks about Russian aggression because Kremlin imperial ambitions didn’t stops and Ukraine still remain the main target of Russian aggression.
