Turkish Foreign Minister Mevlut Cavusoglu warned that Ankara would back out of an agreement to stem the flow of irregular migrants to the EU if Brussels failed to deliver visa-travel for its citizens by October.

"But all that is dependent on the cancellation of the visa requirement for our citizens which is also an item in the agreement of March 18," Cavusoglu said in comments published in the Monday edition of the German daily "Frankfurter Allgemeine Zeitung."

"If visa liberalization does not follow, we will be forced to back away from the deal on taking back [refugees] and the agreement of March 18," he noted.

Cavusoglu added that while the government had not set a specific date for visa liberalization, "it could be the beginning or middle of October."
