Turkish President Abdullah Gul revealed Tuesday that Turkey and Russia have been engaged in closed-door discussions concerning Armenia since Ankara and Yerevan signed the Turkey-Armenia protocols in October.

Gul made the revelation during an interview broadcast on CNN Turk. He stated that "silent, yet very active diplomacy" has been occurring between Turkey and Russia, focusing on a political settlement of the Nagorno Karabakh conflict.

"While we are raising the frozen conflicts, making the process open would only complicate it," Gul told CNN Turk, explaining why details of the discussions are being kept under wraps.
