Two parked car bombs struck simultaneously in separate areas in Baghdad on Wednesday, killing at least six people and wounding 15, police said.
One of the blasts was targeting a transit area in central Baghdad where people can catch minibuses to predominantly Shiite neighbourhoods in the capital.
The attack, occurred at 12:45 pm on the Jamhuriyah Street near the busy Shorja market, killed four people and wounded 12 others, police said.
About the same time, another car packed with explosives blew up in the religiously mixed neighbourhood of Maamoun in western Baghdad, killing two civilians and wounding three others, police said, adding the target of the attack was not immediately known.
Insurgents have stepped up bombings in the capital in recent weeks as they seek to maximise the number of people killed before a planned US-Iraqi security crackdown gets under way.
Shorja, one of Iraq's largest markets, has been struck frequently by bombings, including one on November 21 that killed 25 civilians.
A car bomb also struck a predominantly Shiite area in eastern Baghdad earlier today, killing one person and wounding six, police said.
The explosion occurred at 10 am after the driver parked the car near a currency exchange office in the Amin district in New Baghdad neighbourhood, then walked away.
Police found the body of one person killed thrown into a nearby alley by the force of the blast, while six others were wounded.
