A car bomb targeting army recruits killed at least eight people in Baghdad on Sunday, while six died in other blasts in the Iraqi capital, security and medical officials said.
Recruits gathered at a taxi and bus station in the Allawi area of Baghdad bore the brunt of the blast, which also wounded at least 12 people.
The attack followed a suicide bombing targeting army recruits in the capital on Thursday that killed 23 people.
Militants opposed to the Iraqi government frequently target security forces with bombings and shootings.
In the Kadhimiyah area of Baghdad, another car bomb exploded in a main square on Sunday, killing five people and wounding at least 14.
And a roadside bomb in the Mansur area of the capital killed one person and wounded at least two.
Violence in Iraq has reached a level not seen since 2008, when the country was emerging from a period of brutal sectarian killings.
More than 420 people have been killed in fighting and attacks so far this month, according to AFP figures based on security and medical sources.
