A bomb exploded under a civilian car, killing a man and his wife in southern Baghdad, police captain Nazhan al-Khedr said. 

He said two other people were injured and seven others injured in a bomb explosion near a marketplace in al-Madaen, south of Baghdad. 

No group has yet claimed responsibility for the attacks. 

In recent months, devastating bombings -- often featuring explosive-laden vehicles -- have become commonplace in Iraq’s violence-prone capital. 

The Iraqi authorities typically blame such attacks, which frequently target civilian areas, on the ISIL terrorist group, which captured large swathes of territory in northern and western Iraq in 2014.
