Police officials say a bomb exploded today near a small restaurant, killing four people and wounding nine others in northwestern Baghdad.
A separate bomb blast near a wholesale fruit and grocery market killed three people and wounded 12 others in a southern Baghdad suburb.
Medical officials confirmed the casualties. All officials spoke on condition of anonymity because they were not authorised to brief the media.
Iraq sees near-daily bombings and other attacks mainly targeting Shiite neighbourhoods, security forces and Sunnis allied with the government.
The attacks are often claimed by the Sunni extremist group calling itself the Islamic State, which seized much of northern and western Iraq in a summer offensive.
