Thursday's carnage in the capital's Karradah area came on the heels of bloodshed late Wednesday that included four car bombs exploding within minutes of one another. At least 23 people were killed in western Baghdad's Shula neighborhood and a nearby suburb. Nineteen were killed in Shula alone.
The attacks served as a chilling reminder of how potent militants remain in the capital despite around-the-clock American and Iraqi troop patrols.
Most residents of Karradah and Shula are from Iraq's Shiite majority, while the insurgents are almost exclusively Sunni Arabs, a minority that dominated Iraq until Saddam Hussein's ouster two years ago.
The explosions both days were carried out at times when large crowds were on the capital's streets. Wednesday night's bombs came hours before an 11 p.m. curfew, when many residents are out at eateries or chatting on the streets before locking themselves inside their homes.
In other developments:
Thursday's twin explosions took place when many are just beginning their daily routines. The attacks in Karradah happened nearly simultaneously, police Lt. Col. Salman Abdul Karim and officer Ahmed Hatam al-Sharie said. Five police officers were among the 15 dead.
A young boy, his left leg missing from below the knee, sat on the sidewalk near a mangled bicycle, screaming as a man tried to comfort him. The force of the blasts blew off store shutters, and the surrounding sidewalks were covered with debris, including shattered glass, concrete slabs and charred vegetables and fruit.
