Iranian soldiers took control of an Iraqi oil well on a disputed section of the border on Friday, triggering the ire of Baghdad which demanded their immediate withdrawal. "Iraq demands that Tehran pulls back the armed men who occupied well No. 4... because what happened today is a violation of Iraqi sovereignty," government spokesman Ali al-Dabbagh told a foreign news agency. An official of the state-owned South Oil Co in the southeastern city of Amara, west of the field, said earlier that "an Iranian force arrived at the field early this morning (Friday). "It took control of Well 4 and raised the Iranian flag even though the well lies inside Iraqi territory," the official added.
