“Holding a referendum on the Kurdistan region’s independence from Iraq stirred grave disagreements between the central government and the government of Kurdistan,” Masum, himself a Kurd, said in a televised address.
That “led to federal security forces retaking direct control of Kirkuk,” he said.
Iraqi Kurds voted overwhelmingly on September 25 for independence from Baghdad.
Regional president Masoud Barzani had pushed ahead with the poll in defiance of Baghdad, Washington and Iraq’s neighboring states.
Masum, who belongs to a rival Kurdish party long at odds with Barzani, said the central government had made “strenuous efforts to reach a solution.”
But, he said, a “grave crisis... broke out between the federal government and the government of Iraqi Kurdistan because the latter insisted on unilaterally holding the referendum.”
