A car bomb near an ice-cream shop in Baghdad killed 12 people on Saturday, while seven died in other attacks, officials said, bringing the October death toll to more than 420.
The car bomb in the Mashtal area of east Baghdad also wounded 23 people, interior ministry spokesman Brigadier General Saad Maan told AFP.
In Sinjar, west of the northern city of Mosul, militants shot dead a mother and three sons, all members of the Yazidi religious sect, at their home.
And a bomb near a house in Baquba, also north of Baghdad, killed two members of the same family and wounded five, while gunmen killed one Sahwa anti-al Qaeda fighter and wounded another in an attack on a checkpoint near the city.
