The Iraqi sources said two rockets were fired Tuesday at Ain Al-Asad airbase in Anbar province hosting Americans, in the third such attack in three days as a US government delegation is visiting the country.

Iran Press/Middle East: The two rockets fell on an unoccupied segment of the Ain al-Asad airbase, “without causing damage or casualties,” the Iraqi army said in a statement.

The statement gave no further details.

No causalities were registered until the moment.

A security source confirmed that two Katyusha rockets landed in an empty square at the Ain Al-Asad airbase.

The attack came amid a visit to Iraq by a high-level US delegation, led by White House Coordinator for the Middle East and North Africa Brett McGurk, to discuss a military withdrawal from the country.

No group has claimed responsibility for the attack.

Ain al-Assad accommodates US troops and was visited by former President Donald Trump on Dec. 26, 2018.

The spokesman for Operation Inherent Resolve, the multinational military coalition against the Islamic State group, tweeted that the Ain al-Asad airbase in Anbar province, Iraq, was targeted Tuesday by a rocket attack. Col. Wayne Marotto said two Katyusha rockets landed in “an empty square” on the airbase, which houses US personnel, causing no casualties and inflicting “no material losses.”

The latest rocket attack follows one against an airbase at Baghdad airport housing US-led coalition troops on Sunday night, and another against Balad airbase, which hosts US contractors, north of the capital on Monday night.
