A security source told Rudaw on the condition of anonymity that several people were injured in the shooting, including police officers.
Helicopters hovered over the city and police were searching nearby neighbourhoods to find the perpetrator, according to a Rudaw reporter on the ground.
Duhok police said in a post on Facebook that the perpetrator had been arrested without providing information on the incident.
