Iraqi Prime Minister Haider al-Abadi accepted an invitation from French President Emmanuel Macron on Friday to come to Paris on October 5 for talks on the Kurdish independence referendum, a source in Macron's office said.
An Abadi adviser, who asked to remain anonymous, told AFP that the premier was referring to either an internal or external attack.
An Iraqi force is also deployed on the Turkish side of the border as part of joint drills with the Turkish army.
Most global carriers who fly to and from airports in the Kurdish region announced they would halt flights beginning Friday night in line with the ban.

Iraq's Transport Ministry ordered global airlines to halt service to Irbil, the Kurdish regional capital, and Sulaimaniyah, its second city, beginning Friday evening.
He said the ban would exclude humanitarian and other "urgent" flights."The vote was a historic and strategic mistake by the Kurdish leadership", Al-Abadi said during a press conference in Baghdad.
Two days later, Iraq's parliament called the referendum vote 'unconstitutional'.
