Biden made no public statement about the meeting, though the two leaders presumably discussed the Obama administration's plan to withdraw roughly 140,000 troops from Iraq. The visit was not officially announced.
The vice president-elect's visit came as at least 10 people were killed in a series of bomb attacks against Iraqi security forces, as the Associated Press reports. Violence is down in Iraq but near-daily attacks continue.
By the close of 2011, the vast majority of U.S. troops are scheduled to have been withdrawn from Iraq, with the task of maintaining stability handed over to the country's security forces.
