At least 11 people have been killed in a suspected suicide car bomb attack near a Shia mosque in the Iraqi capital, Iraqi police have said.
More than 40 others were injured in the blast in the Shaab district in the north-east of Baghdad.
The blast happened as worshippers were leaving the Shuruqi mosque after their evening prayers.
Iraq has been hit by a wave of sectarian violence in recent weeks that has claimed hundreds of lives.
The explosion happened at about 2000 local time (1600 GMT), police officer Ali al-Obaidi was quoted as saying by the Associated Press news agency.
The car was driven by a suicide bomber, he added.
The blast occurred several hours after US Secretary of State Condoleezza Rice and British Foreign Secretary Jack Straw ended their surprise visit to Baghdad.
They ended their visit with a joint appeal to Iraqi politicians to move forward quickly on forming a government of national unity - particularly in resolving the current deadlock over its leadership.
The BBC's Mike Wooldridge in Baghdad says to many in Iraq the latest attack only reinforces the case for ending the political vacuum that has existed since the December elections.
