Several blasts shook the Baghdad area hours after a huge funeral procession for a top Iranian general killed by a US airstrike on Friday.
A projectile hit the Green Zone near the US embassy while several more were fired north of the Iraqi capital at Balad airbase, which houses US forces.
BBC News reports nobody was hurt in the attacks.
Iranian leaders have vowed to avenge the killing of Qasem Soleimani, who was regarded as a terrorist by the US.
Soleimani spearheaded Iran's Middle East operations as head of the Quds Force which specialises in unconventional warfare and military intelligence operations.
The strike was directed by US President Donald Trump.
In response to Iranian threats of revenge, the US has sent 3,000 more troops to the Middle East and advised its citizens to leave Iraq.
