US president Barack Obama made an unannounced visit to Baghdad today, marking a new chapter in his strategy to wind down the unpopular war in Iraq and shift the United States' military focus to Afghanistan.
The White House said that Mr Obama would meet US commanders and troops. He would also speak to Iraqi leaders, but would call by telephone rather than see them in person because poor visibility prevented helicopter travel around the capital, White House spokesman Robert Gibbs said.
Flying secretly from Istanbul at the end of his first major international tour, Mr Obama was to visit the scene of a war that he inherited from his predecessor, George W Bush.
It was his first visit to Iraq since before his November 2008 election victory, which was bolstered by his campaign pledge to start bringing US troops home.
Air Force One touched down at Baghdad International Airport a day after a string of seemingly coordinated bombings across the Iraqi capital killed 37 people.
Today, a car bomb killed nine people and wounded 20 in the Shia Kadhimiya district of northwest Baghdad, police said.
The attacks underscored security challenges as the US military prepares to implement Mr Obama's order to withdraw all combat troops by August 2010.
Asked why Mr Obama had come to Iraq, Mr Gibbs said "there are several important reasons, not the least of which is to see and spend some time with the men and women who are serving our country honorably here."
Less than three months into his presidency, Mr Obama was intent on reassuring US commanders he shares their concerns over preserving security gains and making sure troops do not feel forgotten as their numbers are drawn down.
The sectarian warfare and insurgency unleashed by the 2003 US-led invasion have receded dramatically over the past year, but Iraqi security forces still face huge challenges as they take on policing and military operations from the United States.
During his brief visit, Mr Obama was to meet with General Ray Odierno, the top US commander in Iraq, address troops at Camp Victory, and speak to Prime Minister Nuri al-Maliki and President Jalal Talabani.
"We all know that throughout the next many months the solution to the challenges of Iraq lie in political solution," Mr Gibbs said.
"That's why the president is anxious to talk to Prime Minister al-Maliki and President Talabani."
Scaling back troop levels in Iraq will help Mr Obama boost troop numbers in Afghanistan to tackle worsening violence. He had accused Mr Bush of being too fixated on Iraq to focus on the more vital fight against Islamic militancy in Afghanistan.
Despite the switch in priorities, Mr Obama chose Iraq instead of Afghanistan for his first visit to a war zone as US commander-in-chief, a decision made easier since he was already in neighboring Turkey.
With a withdrawal timetable now in place, Mr Obama's visit was aimed at giving him a first-hand look at how his exit strategy is playing out on the ground. Mr Obama has also made clear he will press al-Maliki's government to keep its part of the bargain, from expanding security forces to pushing through further political reforms.
