Dozens killed in Iraq mosque bomb 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. The funeral had been for Oghlu's brother-in-law, who killed in Tuz on Tuesday. Tuz Khurmatu lies in a tract of disputed territory that Kurdistan wants to incorporate into its autonomous three-province region against the wishes of the central government in Baghdad. The row is regarded by diplomats and officials as the greatest long-term threat to Iraq's stability. The death toll from Wednesday's blast was the highest from a single attack since a series of bombings north of Baghdad in July killed 42. Also on Wednesday, gunmen killed a school principal near the main northern city of Mosul and an anti-Qaeda militiaman was shot dead near the predominantly Sunni town of Fallujah. Wednesday's violence came after a wave of attacks on Tuesday killed 26 people and wounded dozens more. That broke four days of relative calm following a spate of incidents claimed by al-Qaeda's front group that killed at least 88 people on January 15-17, according to an AFP tally. The militant group is widely seen as weaker than during the peak of Iraq's sectarian bloodshed, but is still capable of carrying out mass-casualty attacks on a regular basis. The latest wave of violence means the overall death toll from bloodshed in Iraq this month has already surpassed that of any of the previous three months, according to an AFP tally based on reports from security and medical officials. Attacks in Iraq are down from their peak in 2006-2007, but they are still common across the country. The unrest comes amid a political crisis that has pitted Maliki against several of his erstwhile government partners, less than three months before provincial elections.
