A suicide bomber blew himself up in the middle of a funeral at a Shi'ite mosque north of Baghdad on Wednesday, killing 42 people and wounded 75. No group has claimed responsibility.
The bombing occurred at the Sayid al-Shuhada mosque in Tuz Khurmatu, 175km north of Baghdad, at the funeral of a relative of a politician who was shot dead a day earlier.
Among those hurt were officials and tribal leaders, including Ali Hashem Oghlu, the deputy chief of the Iraqi Turkman Front and a provincial councillor in Salaheddin.
AAP reports the funeral was for Oghlu's brother-in-law, who killed in Tuz on Tuesday.
Tuz Khurmatu is a tract of territory that Kurdistan wants to incorporate into its region. Thedispute is regarded as a long-term threat to Iraq's stability.
Attacks in Iraq are down from their peak in 2006-2007, but they are still common across the country.
