Two Katyusha rockets hit Baghdad's fortified Green Zone early on Sunday as Saudi Arabia said it destroed two drones launched by Iran-backed Yemeni Houthis.
One rocket was destroyed in the air by the C-RAM defense system and the other landed near the zone's festivals arena damaging two cars, the report added.
Security forces started an investigation to detect the launch site, the agency reported.
Saudi Arabia also reported that its air defences on Sunday destroyed two drones launched by Yemen's Houthis toward the Abha international airport in the southwest of the kingdom.
A US military official told Reuters that the C-RAM system brought down one of the rounds and none of them landed on the US embassy. The official said there were no American casualties.
The Green Zone hosts foreign embassies, including the US embassy, and government buildings and is regularly the target of rockets fired by groups that US and Iraqi officials say are backed by Iran.
US officials have said Iranian-backed militia could increase attacks on US troops in Iraq and Syria in coming weeks, in part to mark the anniversary of the killing of top Iranian general Qasem Soleimani and Iraqi militia commander Abu Mahdi al-Muhandis.
The two were killed by a US drone strike in Baghdad on January 3, 2020.
