WASHINGTON, Feb. 19 (Xinhua) -- The Untied States said Tuesday it is continuing to work with Turkey on fighting against the Kurdistan Workers' Party (PKK) and calls for cooperation between Turkey and Iraq in fighting the rebel threat.

    "We are continuing to work with the Turkish government and Turkish military to provide the best possible intelligence so that the terrorist group, PKK, operating in Iraqi territory can be dealt with," State Department spokesman Sean McCormack said.

    "Ultimately, what we're looking for is cooperation between Turkey and Iraq in fighting this terrorist threat. And we're going to do what we can, as an interested party with good relations with both sides, to make sure that there is an open dialogue and good communication and effective action in dealing with the PKK," he said.

    The United States has said the PKK is a threat to Turkey, Iraq and the United States, and has voiced support for Turkey to launch attacks on PKK targets in northern Iraq.

    The Turkish military has launched several cross-border attacks to fight separatist PKK rebels, who use northern Iraq as a launch pad for attacks against Turkey.

    The PKK, listed by the United States and Turkey as a terrorist group, took up arms against Turkey in 1984 with the aim of creating an ethnic homeland in the southeast of the country. More than 30,000 people have been killed in the over-two-decade conflict.
