There are rising tensions in Baghdad between the federal and Kurdish regional governments. Not only has Parliament asked the government attempt to capture Kurdish held oilfields, the Iraqi military is now coordinating militarily with Iran. Turkey has so far resisted shutting the border down but could do so at any time. Also, flights into Kurdistan airports are drying up, but that could prove too costly for some foreign governments to maintain long.
Even though their neighbors appear to be overreacting, the Kurds have always maintained that the independence referendum is non-binding. The most they expect of it is to use it to demand dialogue with Baghdad, Ankara, and Tehran over the peaceful transition to full independence. Turkey and Iran have large Kurdish populations, however, that their respective governments do not want considering independence for themselves.
The Syrian government is currently trying to lure Kurdish citizens back into the fold by discussing autonomy within the Syrian nation. Due to the civil war, Kurds in Syria already enjoy autonomy.
A threatened march on contested Kirkuk or an outright operation by Iraqi forces already stationed in the province could mean the start of a long, civil war. The Kurds have a strong military force, the Peshmerga, willing to defend Kurdish interests. Should Turkey and Iran also involve themselves, it could encourage Kurdish rebel groups in those countries to escalate attacks.
Meanwhile in the United States, U.S. Senator Chuck Schumer called for international support for the referendum. However, Prime Minister Haider al-Abadi is demanding the Kurds reject the referendum before he will begin talks.
In news unrelated to the referendum, security forces in Tarmiya, just north of Baghdad, have reportedly imposed a cordon which is preventing necessities from reaching civilians within the city.
