An explosion and fire shut two pipelines that transport oil from Kirkuk to the Turkish port of Ceyhan (pictured) on Friday night, and it was unclear when oil would resume flowing.
Security sources blamed sabotage by Kurdish separatists for the explosion at 11 p.m. (2100 GMT) on Friday near the town of Midyat in Mardin province, near the Syrian border.
Insurgents in Iraq have in the past disrupted the transport of oil on the pipeline, the country's largest, and technical faults on the 35-year-old link, which consists of two pipes, have also cut flows, says Reuters.
