A series of explosions rocked Baghdad on Thursday morning, killing at least nine people and wounding 26, police said. Three car bombs detonated within minutes of each other in front of a grocery store in the southern neighborhood of Dora. At least five people died and 15 were wounded, a police officer said on condition of anonymity because of security concerns. Another bomb exploded in central Baghdad at rush hour, killing four people and wounding 11, two other police officers said. One said the death toll was expected to rise. Both spoke on condition of anonymity because they were not authorized to talk to media. Two of those wounded were policemen, they said.
