BRUSSELS – Defying calls from Moscow, Turkey’s prime minister said Monday that his country won’t apologize to Russia for shooting down a warplane operating over Syria, saying the Turkish military was doing its job defending the national airspace.

Amid high tensions that have elicited concerns from the U.N chief, Ahmet Davutoglu also said Turkey hopes Moscow will reconsider economic sanctions announced against Turkish interests in the wake of last week’s incident. The Turkish resort town of Antalya is “like a second home” to many Russian holidaymakers, he said, but refused to yield on Turkish security.

“No Turkish prime minister or president will apologize … because of doing our duty,” Davutoglu told reporters after meeting NATO Secretary General Jens Stoltenberg in Brussels. “Protection of Turkish airspace, Turkish borders is a national duty, and our army did their job to protect this airspace. But if the Russian side wants to talk, and wants to prevent any future unintentional events like this, we are ready to talk.”

Turkey is a member of the NATO alliance.

U.N. Secretary-General Ban Ki-moon told The Associated Press on Sunday that he’s deeply concerned about tensions between Russia and Turkey after Turkish F-16s shot down a Russian warplane on Nov. 24.
