BAGHDAD — A suicide bomber driving a car packed with explosives detonated the vehicle near an Iraqi military base as soldiers changed shifts north of Baghdad on Tuesday, killing at least 33 people and wounding 56, according to authorities.
The blast struck around midday as troops were leaving the base in Taji, police said. Twenty-two soldiers were among the dead, and several vehicles were damaged, they said.
The casualty toll was high because the attacker blew up the car while large numbers of soldiers were walking to and from a parking area for minibuses waiting to take them to work, officials said.
There was no immediate claim of responsibility, though suicide car bombings are a favorite tactic of Sunni militant groups such as Al Qaeda.
Insurgents frequently target members of the country’s security forces in an effort to undermine confidence in the Shi’ite-led government. Although violence has ebbed in Iraq since the height of the insurgency, attacks still occur frequently.
Officials said many of the wounded were soldiers. They warned the death toll could rise further because several of the injuries were serious.
Tensions at the scene remained high hours after the blast. Police and soldiers cordoned off the area and prevented journalists from approaching. Two cameras were damaged when a scuffle broke out between security forces and journalists who were trying to reach the attack site, a police official said.
