This is Mevlüt Mert Altıntaş – Turkish man who killed Russian ambassador Andrei Karlov.
Mevlüt Mert Altıntaş was born in 1994 in Aydın, Söke, Turkey. He was a special forces police officer in Turkish capital city of Ankara. He was reportedly fired from the force for his alleged involvement in the July 15, 2016 coup in Turkey.
His killing of ambassador Karlov is too reminiscent of the assassination of Archduke Franz Ferdinand in Bosnia, Serbia, that began World War I.
