US Vice President Joe Biden has arrived in Iraq on an unannounced visit. It is his second visit to the country this year.
Biden will celebrate the July 4th weekend with US troops and put pressure on the formation of Iraqi government. He is scheduled to meet with US Army General Ray Odierno, top UN envoy to Iraq Ad Melkert, and Iraqi political leaders.
His visit comes amid Iraq's ongoing political deadlock nearly four months after the country's election and Washington's gradual withdrawal of US troops from the country.
