At least three car bombs have exploded in Baghdad, wounding at least six people.
Iraqi police say the bombs went off almost simultaneously near a market in the southern part of the city.
The violence occurred as Iraqi politicians continued in their efforts to form a new government. Shi'ite, Sunni and Kurdish politicians have been unable to agree on a cabinet. Pressure has been mounting on Prime Minister Ibrahim al-Jaafari, a Shi'ite, to give up his post.
Sunni politicians say Mr. al-Jaafari is a divisive and ineffective leader.
The United States has been pressuring Iraqi politicians to form a new government, which Washington believes will help stem the violence.
Speaking Friday in northern England, U.S. Secretary of State Condoleezza Rice said the United States had probably made thousands of errors in Iraq, but she defended the decision to overthrow Saddam Hussein.
