"No matter how you look at it, this referendum will not bring tranquility, brotherhood, and peace to the region. In this regard, Turkey considers it as null and void," Yildirim said in central Corum province.

He said Turkey will speak directly to Iraq's central government on issues related to borders, airports and economy.

Yildirim also said Turkey would not hesitate to respond to any threats against its national security.

The official preliminary results revealed 93 percent of voters from Monday’s illegitimate referendum backed Kurdish independence, although the vote was widely criticized by the international community.

Monday's illegitimate referendum saw Iraqis in Kurdish Regional Government-controlled areas -- and in a handful of territories disputed between Erbil and Baghdad, including ethnically mixed Kirkuk and Mosul -- vote on whether or not to declare independence.
