ARBIL (Dispatches) -- Iraqi Kurds have rejected a call by the U.S. to postpone a referendum on the independence of their autonomous Kurdish region, planned for next month, according to a high-ranking Kurdish official.
During a phone call on Thursday, U.S. Secretary of State Rex Tillerson had asked Massoud Barzani, president of Iraq's Kurdistan Regional Government (KRG), to postpone the poll over fears it would distract from the fight against Daesh.
But speaking to Reuters on Saturday, Hoshyar Zebari, a close adviser to Barzani, said "The date is standing, Sept 25, no change."
The U.S. State Department said in June it was concerned that the referendum would distract from "more urgent priorities" such as the defeat of Daesh militants. While saying it appreciated the "legitimate aspirations" of the people of Iraq Kurdistan, the State Department said it supported a "unified, federal, stable and democratic Iraq" and had voiced its concerns to Kurdish authorities.
"On the issue of the postponement of the referendum, the President (Barzani) stated that the people of the Kurdistan Region would expect guarantees and alternatives for their future," said the statement issued by the Kurdish presidency after Tillerson's call, giving no further details on the Kurdish leader's reaction to the U.S. request.
Masrour Barzani, head of the Kurdish government's security council and son of President Barzani, sought to allay fears on Friday that the referendum, which is planned for 25 September, would distract from the fight against Daesh.
Seaking in Washington, Masrour Barzani said that the Kurdish government was committed to fighting "terrorism regardless of the political relationship with Baghdad."
"Those opponents who say this is not the right time, my question to them is when is the right time? ... When (Daesh) invaded parts of Iraq and attacked Kurdistan, once again we were told it's a time of war so it’s not the right time. Now that (Daesh) is on the verge of collapse we are again being told it is not the right time," he said.
The U.S. and other Western powers are concerned that the vote could turn into another regional flashpoint. Turkey, Iran and Syria, which together with Iraq have sizeable Kurdish populations, all oppose an independent Kurdistan.
On Saturday, Kurdish officials told Reuters that that September date for the vote would be maintained.
Muqtada al-Sadr, the influential Iraqi Shia cleric, said on Friday that he had urged Kurdish leaders to postpone the referendum.
"Kurds are part of Iraq, and we want them to stay that way, but some issues accumulated from Iraqi governments have led them to depart and reach a level to secede," Sadr told Arsaq al-Awsat.
The referendum, which was called in June, has been a bone of contention among  the Kurds themselves over what territory states will be included in a future Kurdish state.
Sinjar has seen repeated clashes between forces loyal to the KRG and forces linked to the Kurdistan Workers' Party (PKK) who oppose the KRG system of government.
The Gorran movement, an Iraqi Kurdish opposition party with 20 out of 111 seats in the KRG, has said the poll amounts to a power grab by Barzani and would be "illegal" if it goes ahead without the support of other parties.
