A bomb exploded in a busy Baghdad commercial district Wednesday, killing one person and wounding six while a Sunni imam and a counter-terrorism officer died in separate attacks, officials said. The bomb, which was placed in a sports shop, rocked the bustling Al-Rasheed street at about at 1:40 pm (1540 PST) and caused extensive structural damage, said an interior ministry official who gave the toll. The Iraqi capital has been hit by a spate of bomb attacks since a March 7 general election from which no clear winner emerged, leading to fears of a political and security vacuum. Triple suicide bombings on April 4 that targeted foreign embassies and killed 30 people in Baghdad were later claimed by the Islamic State of Iraq, the Al-Qaeda front in the country.
