The Turkish-Iraqi talks, held to discuss measures to prevent a cross-border military operation into northern Iraq to hunt down the rebels who keep their bases there, failed on Friday as Turkey rejected Iraqi proposals, saying they did not satisfy it.
The Turkish parliament sanctioned last week military cross-border operations against the Kurdistan Workers Party (PKK), based in northern Iraq, following an earlier government request.
"Turkey has various means to deal with the PKK. For example, we can continue to use diplomatic means or resort to military means," Turkish Foreign Minister Ali Babacan said during his visit to Iran.
Turkey has by now massed up to 100,000 troops for a possible cross-border military operation against around 3,500 PKK insurgents based in Iraq.
The PKK, listed by the U.S., NATO and the EU as a terrorist organization, has been fighting for autonomy status in southeast Turkey for nearly 25 years. The conflict has so far claimed about 40,000 lives.
