The bomber struck shortly after noon in front of a gathering of Iraqi security forces, killing at least five people and wounding dozens more, a military official said.
A source close to the coalition, speaking on condition of anonymity, said that according to preliminary reports, five rockets hit the Ain al-Assad base in Anbar province.
“Iraqi security forces have responded. No casualties have been reported so far,” the source added.
An Iraqi security source in Anbar reported that three rockets landed near a US-led coalition hosting base against Islamic State jihadists, initially controlled by Iraq.
Rockets and armed drones often target Ain al-Assad bases. The latest such incident on April 30 was when two rockets landed nearby without any casualties.
A previously unknown group, the International Resistance, has claimed responsibility for an attack on a pro-Iranian telegram channel against the US military presence in Iraq.
In recent months, there have been rocket and drone strikes targeting US troops and interests in Iraq. Not many claims are made, but Washington systematically blames pro-Iranian groups for them.
Iraq announced the end of the international coalition’s combat mission last year after helping defeat IS forces.
About 2,500 U.S. troops and about 1,000 troops from other coalition members remain at the three Iraqi military bases to continue a training and advisory role that began more than a year ago.
