Yesterday, US soldiers killed at least 13 people including six Iraqi policemen after coming under fire from a police checkpoint in Baghdad, the US military said.
An Iraqi reporter working for The New York Timeswas also shot dead on his way to work in Baghdad, the newspaper said, a day after two Reuters employees were killed during an incident involving US forces in the city.
Police said 15 people were wounded by today's car bomb near a petrol station in Karrada, a busy Shi'ite neighbourhood in the heart of the capital.
The casualties were among people queuing to get fuel and nearby shoppers, police said.
US and Iraqi security forces have launched a major clampdown in the hope of stemming sectarian bloodshed between minority Sunni and majority Shi'ite Arabs, but violence continues to erupt.
Another car bomb earlier reduced an apartment building to rubble in a Shi'ite district of southern Baghdad.
Police said one person was killed and four others were wounded when a parked minivan filled with explosives blew up next to the residential building.
