Crude oil flows through the Iraq-Turkey pipeline, known as Kirkuk-Ceyhan, stopped on July 21 due to a leak, a regional shipping source said.

The pipeline delivers Iraq's medium sour Kirkuk grade to the Turkish port of Ceyhan on the Mediterranean but it has been mostly down since June 21, when leak problems began. Flows last resumed on July 16.

Around 400,000 barrels remain in storage, but one Turkish tanker has sailed without loading any crude. Four tankers and six pipeline deliveries are now in the shipment backlog. - Reuters
