Addressing a ceremony marking the 7th anniversary of the establishment of the PMU (also known as Hashd al-Shaabi), Kadhimi said the heroes of the PMU and security forces defeated Daesh (ISIL or ISIS) and the Khawarij of the time, al-Ahed News reported.
He added that they continue on the path keeping Iraq secure with professionalism and vigilance.
The ceremony, which was held in Diyala Governorate, also included a parade by PMU forces.
The PMU was formed shortly after the emergence of Daesh in Iraq in 2014.
In November 2016, the Iraqi parliament voted to integrate the PMU into the military.
PMU fighters have played a major role in the liberation of areas held by Daesh terrorists ever since the Takfiri group launched an offensive in the country, overrunning vast swathes in lightning attacks.
