At least two Iraqi police officers have been killed and a civilian has been wounded in the latest spate of attacks in the war-torn country.
Unidentified assailants approached a checkpoint late Thursday in al-Riyadh sub-district, located 55 kilometers (34 miles) west of Kirkuk, and opened fire on the officers stationed there.
A woman bystander sustained injuries as gunmen shot at the security agents, a local police source told the Aswat al-Iraq news agency on Friday.
A medic from a local hospital said he received the bodies of the two police officers killed in the attack.
The armed men escaped the scene in a vehicle and their whereabouts are unknown. Police cordoned off the area after the incident and launched an investigation to establish the motive behind the incident.
Iraqi security forces have been frequent targets of attacks in recent months.
Meanwhile, gunmen killed an official working for the investigation commission of al-Adala Camp in a drive-by shooting in Baghdad's northern neighborhood of Ali al-Saleh on Friday.
Earlier in the day, three Iraqi soldiers suffered different levels of injury when a bomb went off in close proximity to their military vehicle in western Baghdad. Three civilians were also wounded in the bomb attack which took place in the capital's al-Ghazaliya neighborhood.
