"Turkey supports all measures taken in the right direction to stop violence in Iraq and establish security and stability in the country," the foreign ministry said.

The statement also supported as "accurate and constructive" Bush's call to the Baghdad government to ensure that oil revenues are shared by all Iraqis as well as to amend the constitution.

"It is also important that President Bush and the White House... pointed out that the United States will work with Turkey and Iraq against the PKK presence in Iraq," it said.

The ministry was referring to the Kurdistan Workers' Party, an armed separatist group listed as a terrorist organization by both Ankara and Washington, whose militants have long found refuge in northern Iraq.

Turkey is unhappy with the United States for failing to curb the rebels, who, it says, use northern Iraq as a training ground, enjoy unrestricted movement there and easily obtain weapons and explosives for attacks on Turkish territory.

Prime Minister Recep Tayyip Erdogan charged last week that Washington had failed to keep pledges to cut off PKK financing channels and that PKK offices in Iraq remained open despite a September announcement by Baghdad that they would be all closed.

Ankara has threatened cross-border operations into northern Iraq to crack down on the PKK if Iraq and the US fail to take action against the group, which has fought for Kurdish self-rule in southeast Turkey since 1984.
