An Iraqi policeman was killed, three others injured on Tuesday night in a bomb explosion in Kirkuk, a security source told The Baghdad Post on Wednesday.
The source added an explosive charge targeted a police patrol on the main road linking Kirkuk to Riyadh district, leaving one policeman killed and injuring three others.
According to the source, who spoke on condition of anonymity, a security force “carried the trio to a nearby hospital for treatment.”
In October, Iraqi Prime Minister Haider al-Abadi declared that Iraqi troops recaptured Hawija, a main town held by ISIS in the country.
The town had fallen to the ISIS in June 2014, when the militant group seized control of much of northern and western Iraq and proclaimed the creation of a self-styled “caliphate”.
There, ISIS's reign forced thousands to flee to refugee camps, while hundreds had been executed by the group for attempting to escape the area or contacting security forces.
