At least 11 people have been killed as blasts went off in two Iraqi cities.
Six people were killed when a suicide bomber blew himself up in a line of Iraqi recruits queued up to enlist in the second army division in the northern city of Mosul.
Eight people were also injured in the attack on Sunday.
Elsewhere, two consecutive parked car bombs blew up in the central city of Samawa, just south of Baghdad, at a car-plate factory working with the traffic police. Five people were killed and seven injured in that attack.
The deadly bombings come after October was deemed to be the deadliest month in Iraq in five years, with nearly 1,000 deaths. The overwhelming number of those killed were civilians, according to the government and UN figures.
Iraq has been grappling with a spike in violence for months, despite wide-ranging operations targeting armed groups and a major tightening of security in Baghdad and elsewhere.
