General Yasr Buyukanit said the Turkish Army was currently conducting large-scale operations in different parts of southeast Turkey against the separatist Kurdistan Workers Party (PKK), adding 13 Turkish servicemen had been killed in action against the separatists so far this year.
"An operation in North Iraq is imperative. It requires political will," he said, adding the Turkish Army had evidence the PKK plans to intensify terrorist activity in Turkey.
He said terrorism is one of the principal threats to Turkey.
The Turkish chief of staff denied reports that a group of senior Army officers were plotting to overthrow the Tayyip Erdogan government.
"We have no evidence confirming the media reports [about an imminent coup]," he said.
Prime Minister Erdogan said Ankara insisted Iraq meet its demand to crack down on the Kurdish separatists based in northern Iraq.
Over 37,000 people have been killed in the conflict between Turkey and the PKK, which has been fighting for a so called independent Kurdistan in the southeast of the country since 1984.
Turkish authorities are categorically refusing to open dialogue with the separatists and are determined to use force to eliminate the PKK.
