The soldiers then raided a nearby village, capturing 14 alleged armed men connected to the attack.


In a separate raid in another village west of Kirkuk the army captured four suspected al-Qaeda members.


All five of those killed were Kurdish soldiers charged with guarding the country's oil infrastructure running along a corridor of Sunni farming towns west of Kirkuk, which is home to some of Iraq's largest reserves.


In a separate incident, also west of Kirkuk, two more Iraqi army soldiers were killed and another two wounded when their patrol was hit by a roadside bomb, according to Iraqi army Major Sherzad Baziani.
