ISTANBUL -Crude oil flow in an Iraqi pipeline carrying Kurdish and Kirkuk oil to Turkey’s southern port of Ceyhan resumed on Thursday after a week-long shutdown following an attack by Kurdistan Workers Party (PKK) militants, a Turkish energy official and a shipping agent told Reuters. The militants, who have increasingly targeted Turkey’s energy infrastructure, bombed the pipeline last Wednesday. Iraq’s Kurdistan Regional Government energy ministry has said the attacks damaged the region’s economic viability.
