When police arrived at the scene, another bomb went off, killing two police and wounding seven others.

And in Al-Tuz, about 75 kilometres (45 miles) south of the northern oil city of Kirkuk, a magnetic “sticky bomb” on a car killed a policeman while a roadside bomb wounded three civilians, police Major Khaled al-Bayati said.
