An unidentified security source quoted by Saberin News said that two out of five rockets launched hit facilities within the base, which houses maintenance companies employing Iraqi and foreign personnel, and the other three fell outside the compound.
No group or individual has claimed responsibility for the attack on the base so far.
The US base of Al-Balad came under another rocket bombardment on April 4th, but with no casualties.
US facilities in Iraq have been the target of rocket fire or roadside bombs in recent months, as an expression of popular rejection of their presence.
Civil sectors, organizations and parliamentarians demand the total withdrawal of foreign troops, especially from the U.S., whom the Iraqi resistance describes as occupiers.
The assassinations in Baghdad of Iranian General Qassem Soleimani and the deputy commander of the Mobilization Units People of Iraq Abu Mahdi al-Mohandes by the U.S. aviation by order of then-president Donald Trump was followed by a resolution adopted by the Congress of Iraq in January 2020 demanding the expulsion of US forces, subsequently increasing the repudiation of foreign troops on Iraqi soil.
