The US-led coalition fighting Islamic State said on Saturday it did not conduct any air strikes near Camp Taji north of Baghdad.
Earlier on Saturday, Iraq's Popular Mobilisation Forces umbrella grouping of paramilitary groups said air strikes near camp Taji had killed six people and critically wounded three.
Iraqi state television had said they were US air strikes.
"FACT: the coalition ... did not conduct airstrikes near Camp Taji (north of Baghdad) in recent days," a spokesman said on twitter.
The PMF said the attacks hit a convoy of medics, not senior leaders as reported in some media.
