A total of 12,072 polling stations have opened at 8:00 local time (0500 GMT)
Monday where more than 5.3 million are eligible to vote. Polls will remain open
for 12 hours.
The stations are dotted across the three provinces of Arbil, Sulaimaniyah and
Dohuk that form the Iraqi Kurdistan Region as well as in disputed bordering
zones such as the oil-rich province of Kirkuk.
Initial results are expected to be announced 24 hours after the vote.
The non-binding vote on the secession of the semi-autonomous region has irked
the central government.
Baghdad on Sunday urged the world countries not to purchase oil from Kurdistan
Region in response to the referendum hours after Prime Minister Haider al-Abadi vowed
to take "necessary measures” to protect the unity of Iraq.
