An targeted coalition air strike on Monday killed several Islamic State leaders behind suicide attacks in the northern Iraqi city of Kirkuk, local broadcaster Rudaw cited the Kurdistan Region's authorities as saying.
Ahmed Abdulla, whose battle name was Abu Hazifa, was killed together with three other militants, the Kurdistan Region's counter-terrorism department said in a statement.
Hazifa was the alleged IS number one in the Dibs district and many villages in Peshmerga-controlled area, organising many suicide bombings, the department stated.
Other top IS militants have been killed in targeted attacks by coalition jets and Kurdish forces in the oil-rich Kirkuk region, which began in September 2014.
In mid-2015, a Kurdish cleric from Erbil named Mullah Shwan who appeared in several IS propaganda videos was killed in the town of Hawija south of Kirkuk, Rudaw reported.
