BAGHDAD, March 10 (Reuters) - U.S. and Iranian delegates to an Iraqi peace conference in Baghdad on Saturday did engage in discussions, Iraqi Foreign Minister Hoshiyar Zebari said. Iraq called the meeting to enlist support to end violence four years after the U.S. invasion but it was also a rare opportunity for officials from Washington and Tehran to meet at a time of growing tension over Iran's nuclear ambitions. "The issues discussed in the meeting were totally focused on Iraq's security and stability," Zebari said. "There was no other political agenda brought to the meeting." Asked about the interaction between Iranian and U.S. participants, Zebari did not say whether they had met bilaterally but said: "There was meeting, discussions and consultation at times".
