A wave of car bombings in and around the Iraqi capital has killed at least 16 people.

The blasts Tuesday included an attack near an army base in Taji, 25 kilometers north of Baghdad, which killed six people and wounded at least 20 others.

Another car bomb killed five people, including two soldiers, near a security checkpoint in Mahmudiyah, south of the capital.

A third attack hit Baghdad's Shula neighborhood, killing five others.

There was no immediate claim of responsibility for the bombings.

Last week, a string of attacks across the country killed at least 59 people.
