Four people were killed in a suicide bomb attack on Tuesday in the town of Taji, north of Baghdad, according to Iraqi officials, AP reported.
The officials said two soldiers and two civilians were killed in the attack on an army checkpoint.
Two unnamed policemen told AP at least 14 people were left wounded.
Tuesday's attack comes just one day after a suicide bomber struck a group of anti-al-Qaeda fighters in Taji, killing 21 people and wounding 44.
