Baghdad: The United Nations has urged Iraqi Kurdish leader Massud Barzani to drop plans for an independence referendum and enter talks with Baghdad aimed at reaching a deal within three years.

Jan Kubis, the top UN envoy in Iraq, offered international backing for immediate negotiations between the country’s federal government and the autonomous Kurdish region.

In a document seen by AFP, he proposed “structured, sustained, intensive and result-oriented partnership negotiations on how to resolve all the problems and outstanding issues” between Baghdad and Arbil.

The Kurdish Regional Government is embroiled in long-standing disputes with the federal government over oil exports, budget payments and control of ethnically divided areas.

Iraqi Kurdish lawmakers on Friday approved holding the referendum in the face of fierce opposition both from Baghdad and the Kurds’ international backers.

Kubis called for talks, overseen by the UN Security Council, that would aim to reach a deal defining “principles and arrangements” for future relations between Baghdad and the KRG.

In return, Barzani’s administration would agree to postpone the referendum at least until the end of negotiations.

“Here is this offer, if they accept this alternative, there will be negotiations,” Kubis told AFP.

He said he hoped to hear from Barzani “in the next two or three days”.

“I hope they will consider the options and I am waiting for their answer,” he said.

Meanwhile, Iraqi armed forces on Saturday dislodged Daesh from a natural gas-rich border area with Syria, according to the military.

Iranian-backed forces fighting with Syrian President Bashar Al Assad’s army simultaneously announced the start of an offensive to reach the same border area from the opposite side.

An Iraqi military statement said Akashat, a desert region located south of the Euphrates river, was captured in an offensive which had been announced earlier in the day.

The attack on Akashat is meant to pave the way for the recapture of urban centres in the Euphrates valley, including the border post of Al Qaim, it said.

Iranian-backed Shiite paramilitary forces known as Popular Mobilisation and Sunni tribal fighters known as Tribal Mobilization took part in the offensive, it added.

The Iraqi air force dropped thousands of leaflets overnight on Akashat as well as on Al Qaim and the towns of Ana and Rawa, alongside the Euphrates, telling the militants to surrender or face death, the statement said.

Two different campaigns are also advancing on Daesh positions on the Syrian side of the border there — Syrian government forces supported by Russian air strikes and Iran-backed militias, and a US-backed alliance of Kurdish and Arab fighters known as Syrian Democratic Forces (SDF).

An alliance of Shiite militias fighting with the Syrian army said it launched an assault to reach Al Bukamal, the Syrian border town on the Euphrates, facing Al Qaim.

Securing al-Bukamal is important for Iran’s allies as the two other main crossings into Syria, to the north and to the south, are under the control of forces allied with the US.

Securing a land corridor across Iraq could make it easier for Iran to ferry heavy weapons to Syria should Baghdad approve such transfers. The Shi’ite-led Iraqi government in Baghdad has good relations with both Tehran and Washington.

The Russian- and US-backed campaigns against Daesh in Syria have mostly stayed out of each other’s way as the sides seek to avoid conflict, with the Euphrates often acting as a dividing line between them.

But a senior Assad aide this week said the Syrian government was ready to fight the US-backed SDF to recapture the entire country.

The cross-border “caliphate” declared by Daesh in 2014 in effect collapsed in July, when a US-backed Iraqi offensive captured Mosul, the militants’ capital in Iraq.

The towns in the border region with Syria and Hawija, a northern province close to the oil-rich city of Kirkuk, are the only urban centres still under Daesh control in Iraq.

The group overran about a third of Iraq in 2014 in a sweeping offensive that allowed the militants to grab hundreds of millions of dollars worth of weaponry and vehicles left by the fleeing Iraqi forces.
