Sunday’s attacks were the deadliest single-day series of assaults since Oct. 5, when 75 people were killed in violence.
Police officers said that the bombs in the capital, placed in parked cars and detonated over a half-hour period, targeted commercial areas and parking lots, killing 42 people.
The deadliest blasts struck in the southeastern Nahrwan district, where two car bombs exploded simultaneously, killing seven and wounding 15, authorities said. Two other explosions hit the northern Shaab and southern Abu Dashir neighborhoods, each killing six people, officials said. Other blasts hit the neighborhoods of Mashtal, Baladiyat and Ur in eastern Baghdad, the southwestern Bayaa district and the northern Sab al-Bor and Hurriyah districts.
Meanwhile, in the northern city of Mosul, a suicide bomber drove his explosives-laden car into a group of soldiers as they were sealing off a street leading to a bank where troops were receiving salaries, killing 14, a police officer said. At least 30 people were wounded, the officer said. Also in Mosul, police said gunmen shot dead two off-duty soldiers in a drive-by shooting.
In the afternoon, a bomb blast killed four people and wounded 11 inside an outdoor market in the Sunni town of Tarmiyah, 30 miles north of Baghdad, authorities said.
Sunday night, police said mortar shells landed on homes in a Shiite district of Madain, a town just south of Baghdad, killing four people and wounding nine, officials said.
Such coordinated attacks are a favorite tactic of al-Qaida’s local branch. It frequently targets civilians in markets, cafes and commercial streets in Shiite areas in an attempt to undermine confidence in the government, as well as members of the security forces. All of the car bombings Sunday in Baghdad struck Shiite neighborhoods.
