An Iranian delegation that includes the country's top security official left Teheran Sunday for Baghdad for talks with the US on Iraq's security, the official news agency reported. Iran said Monday's talks will include discussions on security, a timetable for US forces to leave Iraq, Iran's participation in Iraq's reconstruction and the presence of the opposition group, MEK, in Iraq, the news agency, IRNA, reported. The ambassador-level talks will include Iranian security chief Muwaffaq al-Rubaii, IRNA said. It did not provide further details. The Baghdad talks, which both sides say will focus solely on Iraq, are the first of their kind and a small sign that Washington thinks rapprochement is possible after nearly three decades of animosity.
