The Iraqi Hezbollah brigades on Saturday denied that any of its members had been wounded in the attacks launched by US fighters Friday on its sites on Friday.
On Friday, the US launched airstrikes on five weapons storage facilities belonging to the pro-Iran group killing three soldiers, two policemen and a civilian.
The US defence department said the airstrikes are in retaliation for a previous attack on the Taji military base near the capital, Baghdad, which wounded two members of the Iraqi Air Force and three coalition soldiers.
The attack is the second in days, after ten rockets landed inside the base, on Wednesday, killing two US soldiers and a British "contractor" and wounding 12 others.
The United States accused the Iraqi Hezbollah brigades of launching Wednesday's attack.
