Insurgents have killed at least 39 people in a wave of attacks against Iraqi security forces, gunning down soldiers at an army post and bombing police recruits waiting in line to apply for jobs, officials said.
The violence, which struck at least 10 cities across the nation, highlighted militant attempts to sow havoc in the country and undermine the government.
There was no immediate claim of responsibility for the attacks, although security forces are a frequent target of al Qaida's Iraqi franchise, which has vowed to reassert itself and take back areas it was forced from before US troops withdrew from the country last year.
In Sunday's deadliest attack, gunmen stormed a small Iraqi Army outpost in the town of Dujail before dawn, killing at least 10 soldiers and wounding eight more, according to police and hospital officials in the nearby city of Balad, 50 miles north of Baghdad.
Hours later, a car bomb struck a group of police recruits queuing to apply for jobs with the state-run Northern Oil Company outside the northern city of Kirkuk. City police commander Brigadier General Sarhad Qadir said seven recruits were killed and 17 wounded. He said all the recruits were Sunni Muslims and blamed the early morning attack on al Qaida, but did not provide details.
The carnage even stretched into the country's south, where bombs stuck to two parked cars exploded in the city of Nasiriyah, 200 miles south-east of Baghdad. The blasts were near the French consulate and a local hotel in the city, although the consulate did not appear to be the target of the attack.
Local deputy health director Dr Adnan al-Musharifawi said two people were killed and three wounded at the hotel, and one Iraqi policeman was wounded at the consulate. He said no French diplomats were among the casualties.
A string of smaller attacks also struck eight other cities, including Baghdad.
In the capital's eastern Shiite neighbourhood of Husseniyah, roadside bombs killed a policeman and a passer-by, security and health officials said. Another eight people - including four soldiers - were wounded, the officials said.
The rest of the attacks were car bombs that hit cities stretching from the southern port city of Basra, Iraq's second largest, to the city of Tal Afar north-west of Baghdad near the Syrian border.
