At least four people were killed and 15 others injured in bomb attacks in this northern province Tuesday, according to a police source.
Six bomb attacks occurred in various districts of Kirkuk while two others were prevented.
No group has claimed responsibility but Iraqi authorities typically blame such acts of violence on the Daesh terror group, which overran one-third of the country in mid-2014.
In 2017, the Iraq army, with the help of a U.S.-led military coalition, recovered most if not all of the territory lost to the notorious terror group.
