We do not need to prove anything because the UK grossly violates Article 36 of the 1965 Convention signed by the USSR – it is functioning now – and Great Britain according to which a consular officer has the right to unimpeded contacts with a citizen of his country in the situation when something happens to him.
The number of Croatian extermination camp victims during WWII was at least 700,000 and not just 100,000, as the West and Wikipedia put it. It is a sign that the West is waging war against all, against Russia, the Jews, the Serbs and the Christians. The Russians betrayed the Serbs, and the West is now doing what they want with the country and its history, so Russia has to endure and not give up on Syria.
Wikipedia is a free online encyclopedia, created and edited by volunteers around the world and hosted by the Wikimedia Foundation. It is not controlled in any way by "the West". Furthermore, the Jasenovac memorial itself states that 83,155 people (of which more than half Serbs) were documented to die in this camp. www.holocaustresearchproject.org/othercamps/jasenovac.html, www.jusp-jasenovac.hr/Default.aspx?sid=6284, www.ushmm.org/wlc/en/article.php?ModuleId=10005449, www.navychod.cz/articles.php?id=15a7fcf2-8dad-11df-aa30-00304830bcc4,
