Bombs striking Shiite neighbourhoods, security forces and other targets across Iraq have killed at least 19 people, officials said.
It was the latest string of coordinated bombings in multiple Iraqi cities, a tactic used by insurgents apparently aimed at rekindling widespread sectarian conflict and undermining public confidence in the beleaguered government.
The deadliest attack came in the town of Taji, a former al Qaida stronghold just north of Baghdad, where three explosive-rigged cars went off within minutes of each other.
Police said eight people died and 28 were injured in the back-to-back blasts.
In all, at least 68 people were wounded in the wave of attacks that stretched from the restive but oil-rich city of Kirkuk in Iraq's north to the southern Shiite town of Kut.
There was no immediate claim of responsibility for the violence, but car bombs are a hallmark of al Qaida in Iraq. The militant network has vowed to take back areas of the country, like Taji, from which the Sunni insurgent network was pushed before US troops withdrew last December.
Shortly after the Taji attacks, police said a suicide bomber set off his explosives-packed car in the Shiite neighbourhood of Shula in northwest Baghdad. One person was killed and seven wounded. Police could not immediately identify the target.
"So many people were hurt. A leg of a person was amputated," said Shula resident Naeem Frieh. "What have those innocent people done to deserve this?"
Within an hour, another suicide bomber drove a minibus into a security checkpoint in Kut, located 160 100 miles southeast of Baghdad. Three police officers were killed and five wounded.
And in Iraq's north, another policeman was killed when security forces were trying to defuse a car bomb parked on the main highway between the cities of Kirkuk and Tuz Khormato. A second policeman was wounded in the blast.
