Two people were killed and four wounded in a bomb explosion in western Baghdad on Thursday, an Interior Ministry source said. 'A roadside bomb went off near the al-Liqaa Sequare in western the capital around midday, destroying a civilian car, killing two people and wounding four,' the source told Xinhua on condition of anonymity. Iraqi security forces sealed off the scene as ambulances evacuated the victims to Baghdad hospitals, the source said. Sporadic attacks continued in Iraq about two months after the country held its landmark parliamentary election which was widely expected to shape the political landscape of the war-torn country.
