Turkish Prime Minister Ahmet Davutoglu on Wednesday said his country would not make any concessions about the security of its borders, after Russian war planes twice violated its air space in the last days.

"We will not make any concessions in the context of our border and air space security," Davutoglu said in televised comments. He also criticised Russian air raids in Syria, saying only two out of 57 bombardments had targeted Daesh (IS) jihadists.
