Ties between Turkey and the United States have been strained to the breaking point by Washington's support for the Syrian Kurdish YPG militia.
"Today (ISIS) does not control a country... in order to assert that they exist, they may carry out an attack any day."
Kurds complain of ethnic, political and economic oppression.
US Defense Secretary Jim Mattis says US is shifting to stabilizing eastern Syria, which will mean more diplomats and contractors.
If the West has any moral integrity and, for that matter, sense of self-preservation, it will throw its full weight behind the Iraqi Kurds.
The battles come after a momentous ten days in Iraq that saw Iraqi Security Forces take over large swaths of territory as Peshmerga withdrew from Kirkuk and Sinjar.
Iraq has deployed its military to assert control over Mount Sinjar, the site of 40 mass graves from ISIS's genocide of the Yazidis who lived there.
Baghdad responded to the Kurdish independence referendum by seizing back the city of Kirkuk, the oil-producing areas around it, and other territory that the Kurds had captured from the Islamic State.
According to local reports the Kurdish forces near Altun Kupri tried to blow up a bridge to slow the Iraqi advance.
The Iraqi central government forces have advanced into Kirkuk province largely unopposed as most Peshmerga forces withdrew without a fight.
