The Turkish army said on Saturday it had killed more than 150 Kurdistan Workers Party (PKK) militants in air strikes at the start of the month. The PKK denied this.
Gul was speaking at a reception in the presidential palace for Europe Day. He did not give further details.
The military had said Turkish warplanes bombed targets in the Qandil mountain region of northern Iraq last Thursday and Friday and said senior PKK members might be among those killed.
In recent months, the Turkish air force has launched regular operations against PKK targets in northern Iraq from where several thousand guerrillas launch attacks into southeast Turkey.
Turkey, the United States and the European Union consider the PKK a terrorist organisation.
Turkish troops conducted an eight-day large-scale incursion across the border in February in which the army said it killed 240 militants and lost 27 Turkish soldiers
