Attackers have blown up a pipeline 60km west of Kirkuk, just a day after repairs to the route connecting the lucrative oil field to a major refinery in Baiji. Northern Oil Company fireman Abd Allah Hamad Ali confirmed the morning attack on Sunday. "The pipeline was only just repaired yesterday, but it has been attacked again." Firemen and police were putting out the blaze, he said. Oil exports from Kirkuk to Turkey have been shut down by incessant attacks.
