Iraqi Kurdish president Masoud Barzani said on Sunday at a news conference in Erbil, that Iraq’s Kurds will go ahead with a referendum for independence on Monday because their partnership with Baghdad has failed.

According to Reuters, Barzani also shrugged off international opposition to the vote.

In response, the Iraqi government asked the autonomous Kurdish region to hand over control of its international border posts, its international airports and called on foreign countries to stop importing Kurdish crude oil, reported Reuters.

Iraqi Prime Minister Haider al-Abadi’s office meanwhile called on “the neighboring countries and the countries of the world to deal exclusively with the federal government of Iraq in regards to entry posts and oil.”

The United States and other Western powers have urged Kurdish authorities in the oil producing region to cancel the vote, arguing that it distracts from the fight against Daesh, Reuters reported.

Turkey and Iran have also kept up the pressure to stop the vote, with presidents Tayyip Erdogan and Hassan Rouhani saying it will “bring chaos in the region”.

The vote, expected to result in a comfortable “yes” to independence, is not binding and is meant to give the Kurdistan Regional Government (KRG) a mandate to negotiate secession with Baghdad and the neighboring countries.

The US embassy in Iraq has meanwhile warned its citizens that there might be unrest during the referendum, especially in disputed areas like Kirkuk, which is also claimed by the Iraqi central government.
