Officials: Suicide bomber kills 4 north of Baghdad
Iraqi officials say a suicide bomber has rammed his explosives-laden car into an army checkpoint north of Baghdad, killing at least four people - two soldiers and two civilians.
Two police officers said Tuesday's attack in the town of Taji also wounded at least 14 people.
A medical official confirmed the casualties. All officials spoke on condition of anonymity because they are not authorized to release information to the media.
Taji is a former insurgent stronghold, located about 12 miles (20 kilometers) north of the Iraqi capital.
On Monday, a suicide bomber struck a group of anti-al-Qaida fighters in the town, killing 21 people and wounding 44.
Violence has ebbed across Iraq since the peak of the fighting, but deadly bombings and shootings still occur almost daily.
