The Vice-President of the United States Joe Biden is holding talks with Iraqi leaders in Baghdad.
It is part of the new role given him by President Barack Obama of administering US policy on Iraq.
Mr Biden is overseeing the US departure from Iraq and also encouraging political reconciliation between its rival power groups.
The White House says Mr Biden will tell Iraqis that Washington will keep to its timetable for full troop withdrawal.
Mr Biden is meeting President Jalal Talabani and Prime Minister Nouri al-Maliki.
He has already met top US military commander Gen Ray Odierno and top US diplomat Ambassador Christopher Hill.
This week US forces completed their pullout from Iraqi cities.
Iraqis celebrated the US troop pullout. However it was also marked on Tuesday by a car bomb attack in the northern city of Kirkuk that killed at least 27 people. http://news.bbc.co.uk/2/hi/middle_east/8132561.stm
