Security officials say two Turkish soldiers have died in clashes with Kurdish fighters in southeastern Turkey.
The officials did not release more detail about the fighting in Kurdish-populated areas near the border with Iraq.
Fighting between Turkish soldiers and the Kurdistan Workers Party or PKK has increased in recent months. In July, Kurdish rebels killed at least 15 Turkish troops in southeastern Turkey.
Turkish Prime Minister Recep Tayyip Erdogan said then that Turkey had the right to mount an offensive against PKK bases in northern Iraq.
The United States opposes a Turkish raid into Iraq and has urged Turkey to work with the U.S. to address the PKK threat.
The PKK began its battle for autonomy in 1984. More than 30,000 people have been killed in the conflict.Some information for this report was provided by AP and Reuters.
