At least 43 people were killed in bomb and gun attacks across Iraq on Thursday, dpa reported.
In northern Iraq, 12 people, mostly children, were killed in a bombing targeting members of a religious minority, police said.
A truck loaded with explosives blew up at a building where members of the Shabak minority lived in the city of Mosul, reported the Iraqi independent broadcaster Alsumaria TV, citing security officials.
The dead included seven children and three women, according to the report. At least 48 were wounded.
The Shabak, who live mainly in the northern Nineveh province and hold beliefs differing from both Islam and Christianity, are considered "infidels" by Islamist extremists.
In the capital Baghdad, at least nine car bombs went off, killing more than 25 people and injuring at least 50, according to Alsumaria.
Two civilians were also killed when gunmen opened fire on them in the southern Dora district, the broadcaster reported.
In the disputed town of Tuz Khurmato, 170 kilometres north of Baghdad, police said that four people were killed and 27 injured when a suicide bomber blew himself up inside a cafe.
A sharp rise in attacks in recent months has raised fears of a return to the sectarian violence that pushed Iraq to the brink of civil war in 2006-07.
According to UN estimates, 979 people were killed in September, making it one of the deadliest months in the last five years.
