The US is scrambling to head off a "disastrous" Turkish military intervention in Kurdish-controlled northern Iraq that threatens to derail the Baghdad security surge and open up a third front in the battle to save Iraq from disintegration.

Senior Bush administration officials have assured Turkey in recent days that US forces will increase efforts to root out Kurdistan Workers' party (PKK) guerrillas enjoying safe haven in the Qandil mountains, on the Iraq-Iran-Turkey border.


But Abdullah Gul, Turkey's foreign minister, MPs, military chiefs and diplomats say up to 3,800 PKK fighters are preparing for attacks in south-east Turkey — and Turkey is ready to hit back if the Americans fail to act. "We will do what we have to do, we will do what is necessary. Nothing is ruled out," Mr Gul said. "I have said to the Americans many times: suppose there is a terrorist organisation in Mexico attacking America. What would you do?... We are hopeful. We have high expectations. But we cannot just wait forever."


Turkish sources said "hot pursuit" special forces operations in Khaftanin and Qanimasi, northern Iraq, were already under way. Murat Karayilan, a PKK leader, said this week that a "mad war" was in prospect unless Ankara backed off.




The US is already fighting Sunni insurgents and Shia militias. Analysts say a surge in violence in northern Iraq, previously the most stable region, could capsize the entire US plan. But pressure on the Turkish prime minister, Recep Tayyip Erdogan, is also growing as a result of forthcoming elections. Military intervention was narrowly avoided last summer when he said that "patience was at an end" over US prevarication. Now conservatives and nationalists are again accusing him of not standing up to Washington.


"If they are killing our soldiers ... and if public pressure on the government increases, of course we will have to intervene," said Ali Riza Alaboyun, an MP for Mr Erdogan's Justice and Development party. "It is the legal right of any country to protect its people and its borders."


General Joseph Ralston, the US special envoy dealing with the PKK issue, was less upbeat, admitting that "the potential for Turkish cross-border action" was growing. "We have reached a critical point in which the pressure of continued [PKK] attacks has placed immense public pressure upon the government of Turkey to take some military action. As the snows melt in the mountain passes, we will see if the PKK renews its attacks and how the Turkish government responds ... I hope the Turks will continue to stand by us."

But a Milliyet journalist, Kadri Gursel, said: "The US attitude has really pissed off the government and the army. The US really doesn't understand how exhausted and fed up they are."
