A senior Iraqi army officer, on Wednesday, said that rockets were fired at the Ain al-Assad airbase, which houses US troops in western Iraq.

Speaking on condition of anonymity, the commander said there were no reports of casualties in the attack, the latest in a spate targeting US military and diplomatic facilities in Iraq that have been blamed on pro-Iranian armed groups within a state-sponsored paramilitary force, news agency AFP reported.

US forces, whose 2,500 troops are deployed in Iraq as part of an international coalition to fight the jihadist Islamic State group, have been targeted almost 50 times this year.

As per an AFP report, the US-based SITE intelligence group said that a militant group called Revenge of al-Muhandis Brigade claimed responsibility for the attack. The group vowed to defeat the “brutal occupation”.

The militant group is named after Abu Mahdi al-Muhandis of Iraq’s Hashed al-Shaabi paramilitary alliance, who was killed in a US drone strike early last year along with the revered Iranian general Qasem Soleimani, SITE said.

Late last month, the US carried out deadly airstrikes against pro-Iran fighters in both Iraq and Syria.

On Wednesday, the Ain al-Assad base was attacked by 14 rockets that “landed on the base & perimeter,” coalition spokesman Wayne Marotto wrote on Twitter.

“Two personnel sustained minor injuries,” he added.

The attack also damaged local homes and a mosque.

Iraqi security forces said the rocket launcher had been hidden inside a truck carrying bags of flour.

Across the border in Syria, where pro-Iran fighters have fought alongside the Damascus regime in the decade-old civil war, Kurdish-led forces also reported attempted attacks near a coalition base.

The US-backed Syrian Democratic Forces said they repelled drone attacks near the base in the Omar oil field in the country’s east.

“Our frontline forces against IS and coalition forces in the area of the Omar oil field dealt with drone attacks,” it said, adding that the drones had caused no damage.
