At least four Iraqi soldiers were wounded after rockets struck the Balad airbase north of Baghdad housing US forces, according to Reuters.
The bombs all fell on a runway within the base, the outlet reported, citing two unidentified military sources. There were no immediate reports of casualties.
The Iraqi military acknowledged the attack in a statement shortly after reports of explosions near the base surfaced online, saying eight rockets landed on the Balad airbase.
No one has claimed responsibility so far.
At least four Iraqi personnel were injured in the attack, the statement said, including two officers.
Four days ago, Iran has carried out a ballistic missile attack on airbases housing US forces in Iraq, in retaliation for the US killing of General Qasem Soleimani.
Two Iraqi bases housing US and coalition troops were targeted, one at Al Asad and one in Irbil, It came just hours after the burial of Soleimani, who controlled Iran’s proxy forces across the Middle East.
Iran’s Supreme Leader Ayatollah Khamenei said the attack was “a slap in the face” for the US and called for an end to the US presence in the Middle East.
That was the most direct assault by Iran on the US since the seizing of the US embassy in Tehran in 1979.
Iran’s Revolutionary Guards said the attack was in retaliation for the death of Soleimani on Friday – killed in a missile strike outside Baghdad airport on the orders of President Trump – and warned US allies that their bases could also be targeted.
The US has around 5,000 troops in Iraq tasked with preventing a resurgence of the Islamic State group (IS) there.
