Ankara protested the incident that took place Friday and asked for the immediate release of the Turkish soldiers.
"This is a very serious incident," deputy Chief of General Staff, Gen. Yasar Buyukanit said.
"Such an act coming from a 50 year-old ally has shocked and deeply hurt us," he said.
The raid was set up after an allegation was made that the Turks were preparing an assassination against a Kurdish governor in Iraq, United Press International reported.
Late last night Turkey closed the Habur border gate at the Iraqi-Turkish border. Turkish officials said the closing was due to "heavy traffic" not in retaliation.
