A diplomatic facility of the United States in Baghdad was attacked late on Tuesday, but there are no reports of casualties, and a damage assessment is currently in progress, according to a statement from a US embassy spokesperson on Wednesday.

Security sources reported that two rockets landed around 11pm on Tuesday near US forces stationed near Baghdad airport at the Camp Victory base.

"At approximately 23.00 on Tuesday, September 10, there was an attack at the Baghdad Diplomatic Services Compound, a US diplomatic facility," the US embassy statement read. "Fortunately, there are no reported casualties, and we are assessing the damage and its cause. Our assessment is ongoing," it added.

Kataib Hezbollah, one of Iraq's Iran-backed armed factions, suggested that the timing of the attack was intended to disrupt a visit to Iraq by Iranian President Masoud Pezeshkian, which commenced on Wednesday.

The group urged Iraqi security forces in a statement issued early on Wednesday to investigate the attack and identify those responsible.

Pezeshkian, who was elected in July, is on his first foreign trip and is expected to sign several bilateral agreements with Baghdad and discuss the Gaza war and broader Middle Eastern issues with Iraqi leaders.

Iraq, a unique regional partner for both the United States and Iran, hosts 2,500 US troops and also has Iran-backed armed factions integrated with its security forces.

Iran-aligned armed groups in Iraq have frequently targeted US troops in the Middle East since the start of the Gaza war.
