At least 20 Popular Mobilisation Forces (PMF) fighters have been killed and 32 wounded in US-Saudi attacks across Iraq, the group said.
The PMF said the initial death toll could increase as teams continue assessing the affected sites.
The attacks targeted its positions in seven provinces: Baghdad, Wasit, Nineveh, Basra, Kirkuk, Karbala and Diyala.
The state-sanctioned umbrella organisation, which largely comprises Shia armed groups, said the strikes also damaged buildings, vehicles and military equipment.
