A military base hosting US forces has come under fire, according to Iraq's armed forces.
Its military confirmed Camp Taji, where coalition forces are based along with Iraqi troops, has been targeted with rockets, Reuters reports.
It was not immediately clear whether anyone had been injured in the attack, following conflicting reports.
The Iraqi Military has since issued a statement saying there were no casualties after Taji was targeted by Katyusha rockets.
Reports from the region say the camp came under heavy rocket fire.
No group has claimed responsibility for the attack.
On Sunday, four people were wounded after eight Katyusha rockets were fired at Balad air base, which houses US personnel, located about 50 miles north of Baghdad, the Iraqi military said in a statement.
Military sources identified the wounded in that incident as Iraqi soldiers to Reuters.
Tensions are at a high in the Middle East after the US executed top Iranian general Qassem Soleimani.
Iran responded by firing missiles targeting two US military bases in Iraq a week later.
There were no casualties in the attacks.
A Ukrainian Airlines plane crashed shortly after Iran's attacks, killing all 176 aboard.
Iran later admitted the aircraft was mistakenly shot down at the airport near Tehran amid the tensions.
