A car bomb has exploded near a funeral ceremony in a mainly Shia Muslim area of Baghdad, killing at least 30 people, Iraqi officials say.
Another 50 were wounded, they said.
The blast comes after a series of bombings killed dozens of Shia pilgrims during their annual pilgrimage to the holy city of Karbala last week.
A spate of bombings in the past month against pilgrims, police recruits and security forces across Iraq has killed more than 170 people.
The car that exploded on Thursday was parked near a funeral tent in the capital’s north-western Shula district, an interior ministry source said.
The recent rise in violence comes as the US military prepares to withdraw from the country at the end of the year.
This poses a major challenge to Iraqi Prime Minister Nouri al-Maliki and his fragile coalition government, formed only last month.
In other parts of the capital on Thursday, three roadside bombs claimed the lives of three Iraqis, including a policeman.
Violence has declined sharply in Iraq since the height of the sectarian killings of 2006-2007, but near daily attacks continue.
