A suicide bomb blast has killed at least two Iraqi police and wounded a senior intelligence officer north of Baghdad.
Officials said the bomber hit the convoy of Colonel Qassem al-Anbaki, the head of police intelligence in Diyala Province, at a checkpoint near the city of Baquba on January 12.
There was no immediate claim of responsibility for the attack, which came a day after an Islamic State (IS) attack in a busy shopping area of Baghdad and other blasts around the country claimed at least 35 lives.
The IS group overran large swaths of territory north and west of Baghdad in June 2014.
Iraq declared victory over the IS group in Diyala early last year but that has not brought an end to attacks by the militants.
