Recep Tayyip Erdogan is not a man who would be afraid of death threats, turn away from his path and his cause
During Sunday's visit, Erdogan will hold bilateral and inter-delegation talks with Bakir Izetbegovic, the Bosniak member of the tripartite Presidency of Bosnia and Herzegovina, during his visit, according to a statement by the presidential press office.
