In this Thursday, July 31, 2014 file photo, a column of smoke rises from an oil refinery in Beiji, some 250 kilometers (155 miles) north of Baghdad, Iraq, after an attack by Islamic militants. Iraqi soldiers battling the Islamic State group recaptured the heart of the town of Beiji, home to the country's largest oil refinery, state television and a military official said Tuesday, Nov. 11, 2014. Retaking Beiji, could allow Iraqi forces a base to attack neighboring Tikrit, taken by the extremists after their lightning advance this summer. (AP Photo, File)
