The 10:00 am blasts in Saadiyah came a day after a suicide bomb in the nearby town of Khanaqin killed 30 people, with Iraq due to hold its first parliamentary elections since 2010 tomorrow.
Saadiyah lies in eastern Iraq, along a tract of disputed territory that the country's autonomous Kurdish region wants to incorporate despite Baghdad's objections.
Militants frequently capitalise on poor communication between Kurdish and Arab security forces in the disputed areas to launch attacks.
Prime Minister Nuri al-Maliki, who hails from Iraq's Shiite Arab majority and is accused by critics of monopolising power and targeting minority groups, is seeking a third term in tomorrow's election.
