Iraq's interior minister on Wednesday acknowledged the existence of so-called death squads within certain security forces but denied any link with his own ministry.
Bayan Jabr Solagh, in an interview with the BBC, pointed the finger at special security forces that provide protection for ministries and key installations, as well as the myriad private security companies in Iraq.
Asked if there were unofficial death squads operating within these security forces, he replied: "Sometimes, yes, I can tell you... with these security companies it is not right... you do not know what they are doing.
"We have to make clear that there are some forces out of order, not under our control and not under the control of the ministry of defence," he said.
"These forces are the FPS to protect the ministries," he said, referring to special security forces known as Force Protection for Site (FPS) which protect ministry buildings, power stations or oil pipelines.
"And their numbers are huge... there are 150,000," he said.
"Their uniform is like the police, their car is like the police, their weapons are like the police."
A recent upsurge of sectarian violence in Iraq that has left hundreds of dead is often blamed by Sunnis on militias wearing uniforms belonging to the security forces.
"Terrorists or someone who supports the terrorists... are using the clothes of the police or the military," Solagh said in comments published on the BBC website.
"Now you can go to the shop and buy it."
