Baghdad - At least two Iraqis were killed Wednesday and another 20 were wounded in four separate attacks in the Iraq's capital Baghdad, security and police sources said. In Baghdad, one civilian was killed and seven others were injured when a bomb went off in the Komb Sara area, security sources told the Voices of Iraq (VOI) news agency.
Few minutes later, another bomb was detonated near a gas station in Baghdad's Benook district, injuring two civilians.
In the capital's Shiite-dominated Kazimiyah district, a bomb went off on a bus injuring four passengers, police sources told VOI.
In another incident, one person was killed and another seven were injured when a bomb exploded in Baghdad's Karada district, security sources told Deutsche Presse-Agentur dpa.
Separately, US troops arrested on Wednesday a suspected special group explosives expert in Numaniyah, 180 kilometres south-east of Baghdad near the city of Kut, according to a US military statement.
The military uses the term "special groups" to describe Shiite fighters breaching a truce order issued by radical cleric Moqtada al- Sadr, whose militia fought Iraqi and US troops for months until the truce was reached in May.
Acting on intelligence from other Shiite militiamen already in detention, US soldiers captured the expert, who is believed to have travelled to Iran several times for training, the military said.
Troops entered the suspect's home and subdued him without firing any shots, according to the statement.
The Iranian government denies long-standing US allegations that Tehran arms, funds and trains Shiite militiamen in Iraq.
Iraqi Prime Minister Nuri al-Maliki, himself a Shiite, discussed during a visit to Tehran last weekend the US arrests of fighters allegedly trained by Iran.
