A suicide bomber has set off a car packed with explosives at an army checkpoint in Iraq, killing at least four people and wounding 12 others.
The attack Tuesday happened in Taji, about 20 kilometers north of the capital, Baghdad. At least two soldiers were among those killed.
There was no immediate claim of responsibility for the attack.
The bombing is the second such attack in as many days in Taji. On Sunday, a suicide bomber targeting government-backed forces killed at least 22 people.
