A bomb attack halted crude flow through the pipeline running from Iraq's Kirkuk oilfields to the Mediterranean port of Ceyhan in Turkey, officials at Iraq's North Oil Company (NOC) said on Sunday.
The attack took place at midnight on Saturday near the city of Mosul and the officials at state-run NOC said repair work would be complete in 72 hours as long as there were no further security issues.
The incident is the latest in a string of attacks across Iraq, leaving more than 2,900 people dead since the start of April.
In the first 16 days of the holy month of Ramadan, more than 400 people have lost their lives in violence across Iraq.
International human rights attorney Edward Corrigan said that foreign powers are attempting to fabricate sectarian discord in Iraq and elsewhere, with the ultimate aim of weakening the Muslim world.
Kirkuk–Ceyhan Oil Pipeline is a 600-mile (970 km) long pipeline. It is Iraq's largest crude oil export line.
