Iraqi Deputy Oil Minister for Upstream Affairs Basim Mohammed told Reuters that the Kirkuk-Ceyhan pipeline, which has been closed for a decade, is likely to restart flows by the end of April.

"Repair works are ongoing, and a major crude pumping station with storage facilities has been completed,” he said.

Mohammed added that repairing damaged parts of the pipeline in Iraq and finishing the pumping station will be the first stage of operations to bring the pipeline back to full capacity.

The Iraqi government's mothballed section of the 960-kilometer (600-mile) pipeline, which once handled around 0.5% of the global oil supply, has been closed since 2014 after Islamic State militants attacked it. Baghdad will require oil companies to negotiate with the Iraqi government to sell their oil via the revived pipeline.
