Last week, Iraqi lawmakers voted against the independence referendum and called on the Baghdad government to negotiate with the Kurdish Regional Government.
The Iraqi Kurds plan to hold the referendum on September 25 in three governorates that make up their self-ruled region, as well as in disputed areas that are controlled by Kurdish forces but claimed by Baghdad, including the oil-rich province of Kirkuk. The court's move came in response to lawsuits challenging the planned vote.
Despite strong opposition from Baghdad, regional leaders and the United States - a key ally of Iraq's Kurds - Kurdish officials have continued to pledge the vote will be held.
The outlawed PKK has been waging an insurgency in Turkey's southeast, bordering Iraq and Syria, for more than 30 years.
"Iraq's integrity is a red line that can not be violated", Hakim said in a meeting with Iraqi tribal leaders in southeastern Wasit province.
The United Nations and the USA as well as regional powers like Iran and Turkey have also expressed concerns about the planned referendum by the semi-autonomous KRG, arguing that it could create further instability in the already volatile region.
The Prime Minister also announced that the government is prepared to intervene militarily if the Kurdish region's referendum results in violence.
Iran-backed Iraqi Shia militias have threatened to dislodged the peshmerga from Kirkuk should the Kurds proceed with the vote.
The army was training tank guns and rocket launchers across the southern border on Tuesday, less than a week before a Kurdish independence referendum in northern Iraq.
A Reuters reporter saw four armored vehicles carrying heavy weaponry and soldiers taking positions in specially dug areas, their weapons directed across the border.
Turkish President Recep Tayyip Erdogan and Iraqi Prime Minister Haider al-Abadi had a conversation over the phone to discuss a number of issues which also included the now suspended KRG referendum. The standoff has weakened the Turkish lira beyond 3.5 to the dollar for the first time in four weeks. Despite the nearby military maneuvers a kilometer-long line of traffic, mostly trucks and cargo, queued to enter Iraq at the Habour border gate.
Despite the order, it is unclear whether the local government will pursue the referendum.
"Moreover, the 27 September assembly of Turkey's National Security Council has been rescheduled to September 22 due to Barzani's referendum decision".
