"Turkey will remain in northern Iraq as long as necessary," Gonul told reporters after talks here with US Defence Secretary Robert Gates.

He said Turkey is targeting only rebel fighters of the separatist Kurdistan Workers' Party (PKK) and has "no intention to occupy any area" in the region.

Gates said "a specific timetable did not come up" in the meeting with Gonul and urged Turkey to wrap up its operation as soon as possible.

Turkey's offensive "should be as short and precisely targeted as possible," he said.

Gates is scheduled to meet Prime Minister Recep Tayyip Erdogan, President Abdullah Gul and Chief of General Staff Yasar Buyukanit later in the day.

The American warned Turkey Tuesday that its incursion in northern Iraq should last no more than "a week or two."

Turkish forces stormed into northern Iraq on February 21 to uproot the PKK, which has long used camps in the region as a springboard for attacks inside Turkish territory.
