At least 35 people were killed and 151 others wounded on Tuesday in a wave of violent attacks across Iraq -- most of them in the capital city of Baghdad, the police said. The bombing attacks in Baghdad left at least 26 people dead and 102 others injured, with the deadliest one in the northwestern Shuala area, where two car bombs in a market killed 11 and wounded 39, a police source told Xinhua on condition of anonymity. Four people were killed and 15 others wounded when two car bombs also struck a popular market in the Shaab area in northeastern Baghdad, the source said. Also, a car bomb exploded in the Kamalea area in eastern Baghdad, killing three people and injuring 11 others, while another car bomb went off near a parking garage in the Dora district in the southern part of the city, killing two and wounding 10. Meanwhile, three people were killed and 14 others wounded when a car bomb exploded near a market in the Abu Ghraib area west of Baghdad, the source said, adding that another car bomb attack in the Hurria area in northwestern Baghdad killed three people and injured 13 others. Elsewhere, a car bomb went off in Samawah, some 280 km south of Baghdad, killing three civilians and wounding 20 others, a police source said. Another car bomb on the Tigris Street in Amarah, some 300 km southeast of Baghdad, killed two people and wounded five others, he added. Separate attacks in the northern cities of Baquba and Mosul also killed a total of four people and injured 24 more. No group has so far claimed responsibility for the attacks, but the al-Qaida front in Iraq, in most cases, was responsible for such violent acts in the country. High-profile bomb attacks are still common in Iraq despite the dramatic decrease since their peak in 2006 and 2007, when the country was engulfed in sectarian killings.
