A roadside bomb apparently planted to hit an Iraqi police patrol missed its target and killed one civilian instead Monday in eastern Baghdad, police said. Four others were wounded in the blast, which hit the mostly Shiite Mashtal area during the morning rush hour, police said. Most of the victims were in a civilian car driving behind a police convoy, they said. Across town, another bomb went off early Monday at an Iraqi Army checkpoint near a children's amusement park, police said. No one was hurt.
