Violence across Iraq has killed more than 80 people, including 41 soldiers, and left scores more injured, amid the country's worst protracted period of unrest since 2008.
The bloodshed on Tuesday comes just weeks before Iraq is due to hold its first national vote since 2010, though the poll was thrown into disarray earlier when the entire electoral commission resigned over political interference.
In the deadliest attack, 22 soldiers were killed and 15 others injured in Al-Nibaee village, near Taji city, north of Baghdad.
