Story highlights Turkey makes the request under Article 4 of NATO's founding treaty

It's only the fifth time in NATO history that members will meet under Article 4

The talks are expected to take place Tuesday

(CNN) NATO said Sunday that it would meet this week after Turkey called for special talks amid heightened concerns over its security.

Turkey made the request under Article 4 of NATO's founding treaty, which allows countries to ask for consultations when they believe their territorial integrity, political independence or security is threatened.

It's only the fifth time in NATO history that members will meet under Article 4, NATO spokeswoman Oana Lungescu told CNN.

"In the wake of increased security threats following the attacks against our security and law-enforcement forces in provinces of Diyarbakır, Şanlıurfa and Kilis, in particular the terrorist attack that took the lives of 32 innocent Turkish citizens in Suruç on 20 July 2015, all necessary measures are being taken and in this context, operations are also being carried out by the Turkish Armed Forces," the Turkish Foreign Ministry said in a statement.

"Upon these recent attacks and threats directed against our national security, North Atlantic Council has been called for a meeting by Turkey [this] week under Article 4 of the Washington Treaty with a view to informing our Allies about the measures we are taking and the operations we are conducting against terrorism, as well as to holding consultations with them," it said.
