Baghdad ? Vice President-elect Joe Biden conferred Monday with Iraqi leaders after a trip to Afghanistan, capping a tour of U.S. battlefronts on a day when police reported bombings killed 10 people in Baghdad.

The four attacks were a reminder that major violence may still return, complicating the incoming administration’s plans to draw down troops in Iraq and focus more attention on Afghanistan.

Biden, a frequent visitor to Iraq as a member of the Senate Foreign Relations Committee, met with President Jalal Talabani, Vice President Adel Abdul-Mahdi and deputy Prime Minister Barham Saleh after arriving in Baghdad.
