An Iraqi policeman was killed and two others were injured in an attack in the northern Kirkuk province on Sunday, according to a local police officer.
Armed men staged an armed attack on a federal police checkpoint in Riyadh district, southwest of Kirkuk, the officer said on condition of anonymity because of restrictions on speaking to the media.
The attackers fled the scene unscathed, the officer said, blaming the Daesh/ISIS group for the attack.
Iraqi authorities have yet to confirm the attack, which came one day after the killing of five policemen in a bomb attack targeting their vehicle in Kirkuk on Saturday.
Daesh/ISIS terrorists have in recent months escalated their attacks, especially in the area between Kirkuk, Salahuddin, and Diyala, known as the Triangle of Death.
In 2017, Iraq declared victory over Daesh/ISIS by reclaiming all territories the terrorist group controlled since the summer of 2014, which was estimated to be about a third of the country's territory.
The group, however, still maintains sleeper cells in large areas in Iraq and launches attacks.
