The attack reportedly targeted several SUVs belonging to a leadership committee of the Popular Mobilization Forces, the collection of semi-independent militias tied to the Iraqi government that were formed to fight Daesh in 2014.
A Sky News reporter tweeted in Arabic about the potential deaths of PMF leader Abu Mahdi Al-Muhandis and Muhammad al-Kawtharani, a leader in Lebanon's Hezbollah, but these have not yet been confirmed.
There have also been conflicting reports that perhaps among the dead is Qassem Soleimani, the leader of the Quds Force, an elite unit of Iran's Islamic Revolutionary Guard Corps, but that also remains unconfirmed.
At least eight people are reported dead in the attack, according to Agence France-Presse, citing Iraqi security officials.
The rocket attack comes just days after thousands of Iraqi protesters attempted to storm and set alight the US Embassy in Baghdad, prompting Washington to send 100 US Marines and several Apache attack helicopters to the Iraqi capital from neighboring Kuwait.
Local observers reported that US helicopters were once again in the air following news of the rocket attacks at the airport, which has since been temporarily closed.
