The Dujail attack was one of the deadliest in Iraq in recent months and comes at a time when the violence in Iraq is at a four-year low.

The last major suicide attack occurred on August 26, when a  bomber thwarted a security checkpoint in Jalawla, a police recruiting centre, and blew himself up, killing at least 25 people.

Dujail is a mainly Shia town in the Sunni province of Salaheddin, north of Baghdad.
