And in Dohuk, the capital of an eponymous province in the autonomous Kurdistan region of north Iraq, a magnetic "sticky bomb" wounded two civilians, according to Birendar Hamid Sharif, the head of the Dohuk police media office.
Sharif said that a suspect was arrested in connection with the rare attack in normally peaceful Dohuk.
The latest violence brings the number of people killed in attacks in Iraq so far this month to at least 142, including 63 security force members, according to an AFP tally based on security and medical sources.
While violence has decreased from its peak in 2006 and 2007, attacks remain common across Iraq. There were attacks on 27 of the 31 days in July, and there has been at least one shooting or bombing every day this month.
Official figures put the number of people killed in attacks in July at 325, the highest monthly death toll since August 2010.
