A car bomb killed six people and wounded 10 others on Thursday in southeastern Baghdad, a security source said.
The blast occurred near a Sunni Mosque in Al-Ameen, which lies in the Nissan district, the source said.
In Baquba, northeast of Baghdad, four policemen and a civilian died during an attack on a patrol, he added.
Another seven people died and 12 were wounded late Wednesday when two bombs exploded in Suwaira, south of Baghdad.
The two blasts came a few minutes apart near the office of a group loyal to radical Shiite cleric Moqtada al-Sadr in the center of the town.
The second explosion ripped through a crowd that had gathered to help evacuate victims of the first, the sources said.
