The Turkish foreign minister said Friday his nation was determined to send its troops over the border into northern Iraq to contain a possible refugee flow and prevent any attempt by Iraqi Kurds to break away from Iraq. 

Abdullah Gul's remarks came despite strong opposition in Washington to any unilateral move by Turkey into northern Iraq. U.S. Secretary of State Colin Powell said Friday: "We don't see any need for any Turkish incursions into northern Iraq." 

But "Turkish soldiers will go in," Gul told reporters on his return from a trip from Brussels. 

Gul's statement came after Turkey agreed Friday to allow U.S. overflights for a war with Iraq, reversing an earlier decision to block Turkey's airspace because of a disagreement with the United States over a Turkish troop deployment. 

Washington has warned that a Turkish incursion could lead to friendly fire incidents with U.S. forces. Iraqi Kurdish groups say the move could lead to clashes. 

In Washington, a senior U.S. official, speaking on condition of anonymity, said Turkey opened its airspace without any conditions attached, adding that the U.S. administration continued to discuss the issue of Turkish troops separately. 

Turkey's Defense Minister Vecdi Gonul also said Turkish and U.S. officials would continue negotiations. 

Turkey has frequently sent soldiers into northern Iraq to chase Kurdish rebels belonging to the Kurdistan Workers Party, or PKK, which fought a 15-year battle for autonomy from Turkey. 

Gul said Turkey wanted to prevent Iraq's breakup and to contain a possible refugee flow within Iraq's borders. 

"Turkey's Iraq policy is ... Iraq's territorial integrity, that Iraq's resources are shared by the whole population ... that a refugee flow is contained within Iraq," Gul said. 

"Turkey has no designs whatsoever on Iraq's territory. Turkey will take measures in line with these aims," he said. 

Turkey fears that Iraq could fragment during a war, leading Iraqi Kurds to declare independence, which could encourage Turkish Kurdish rebels. 

Turkey's parliament voted Thursday to allow the United States to use the airspace, a measure that would allow strike aircraft on carriers in the Mediterranean to fly more directly into Iraq. 

The resolution passed by parliament would also allow Turkey to move its own forces into northern Iraq.
