A pair of car bombs has ripped through crowded Nisoor Square in Baghdad, killing 27 people and wounding 50. The targeted building contained an interior ministry office that issues ID cards and many people were lined up outside when the cars exploded. Police and the Trade Bank of Iraq were also in the offices. The blasts were coordinated, with the vehicles parked a few hundred yards apart. Violence has increased in Iraq since the March elections, when a close result prevented politicians from easily forming a government. Three months later, a coalition still has not been formed.
