Two rockets early Thursday slammed into the Iraqi capital's Green Zone, the high-security enclave home to government buildings and foreign embassies, the military said.
Foreign diplomats and troops based across Iraq have been targeted in similar attacks more than two dozen times since late October, according to an AFP count.
Before dawn on Thursday, two rockets punched into an empty square near an Iraqi security headquarters in the Green Zone, the security forces said.
But an Iraqi security source told the media the intended target appeared to be the US embassy, a sprawling compound a few hundred metres further south on the banks of the Tigris.
The Green Zone's sirens could be heard going off shortly afterwards.
There were no reports of casualties.
Earlier this month, two US military personnel and a British soldier were killed in a rocket attack on the Taji airbase further north, which was hit again two days later.
The 5,200 US troops stationed across Iraqi bases make up the bulk of the 7,500-strong coalition force deployed to help local forces beat back jihadist remnants.
Those troops are being drawn down this month, partly as an emergency response to the novel coronavirus pandemic and partly as a more permanent repositioning.
British, French, Australian and Czech forces who were in Iraq to coach Iraqi forces were being temporarily sent home as Baghdad had put a hold on training operations.
Trainers amount to a third of the total coalition troops.
But the coalition is also consolidating its forces into a smaller number of bases across Iraq and sending some troops out of the country in the process.
On Thursday, US-led coalition forces will hand over the northern air base of Qayyarah to Iraqi troops, the second such departure this month.
On Wednesday, three servicemen, including two Americans, were killed when the base was attacked, the deadliest to target US troops in Iraq since a late December rocket attack on an Iraqi base that killed a US contractor and set in motion a series of tit-for-tat attacks that brought Iraq to the brink of war.
The attack threatens a dangerous escalation, with suspected US-led coalition air strikes promptly targeting Iran-aligned Iraqi fighters in neighbouring Syria, a war monitor said. At least 18 fighters were reported killed.
Coalition officials say the troop cuts and relocation of units into fewer Iraqi bases is because Iraqi forces are mostly capable of containing the threat from leftover Islamic State militants on their own.
The Southeast Asian nation is among the world's most open economies and seen as a gauge of the health of the global trade. Last week, it posted a sharp decline in first quarter gross domestic product and slashed growth projections.
Two specially equipped high-speed trains carried 36 patients from Mulhouse and Nancy to hospitals along France's western coast, where the outbreak has been limited so far.
Brought forward by Trump at the outdoor briefing, Fauci said his projection of a potential 100,000 to 200,000 deaths is "entirely conceivable" if not enough is done to mitigate the crisis.
