Washington: The US military struck three facilities in Iraq on Tuesday, targeting an Iranian-backed militia in retaliation for missile and drone attacks on American troops in Iraq and Syria over the past several days, Defense Secretary Lloyd Austin said.

The US strikes hit militia facilities in Jurf Al Sakhar, which is south of Baghdad, Al Qaim and another unnamed site in western Iraq, two US officials said.

“At President Biden’s direction, US military forces conducted necessary and proportionate strikes on three facilities used by the Iranian-backed Kataib Hezbollah militia group and other Iran-affiliated groups in Iraq,” Austin said in a statement. “These precision strikes are in direct response to a series of escalatory attacks against US and Coalition personnel in Iraq and Syria by Iranian-sponsored militias.”

The strikes came hours after the US said militants fired two one-way attack drones at Al Asad Air Base, injuring US service members and damaging infrastructure. And they followed the militia's most serious attack this year on the air base, when it launched multiple ballistic missiles on Saturday.

Headquarters, storage targeted

US Central Command said the US attack targeted headquarters, storage, and training locations for rocket, missile, and one-way attack drone capabilities of the group.

In Tuesday's drone attacks against Al Asad, US defenses were able to intercept the first drone but it crashed on base and the second drone hit the base, US officials said. Injuries, including traumatic brain injuries and smoke inhalation, were reported to be minor. The officials spoke on the condition of anonymity to provide details that had not been announced publicly.

During Saturday's larger-scale attack, multiple ballistic missiles and rockets launched by Iranian-backed militants targeted Al Asad, but most were intercepted by air defense systems there, Sabrina Singh, Pentagon spokesperson, told reporters on Monday. She said other munitions hit the base.

Al Asad is a large air base in western Iraq where US troops have trained Iraqi security forces and now coordinate operations to counter the Daesh group.

Singh said Saturday’s attack was a “barrage.” It was the first time since November 20 that Iranian proxy forces in Iraq had fired ballistic missiles at US bases in Iraq.

Islamic Resistance in Iraq

A coalition of militias calling itself the Islamic Resistance in Iraq has taken credit for a number of the attacks on US forces. Kataib Hezbollah is one of the groups within that umbrella organisation.

But the repeat use of ballistic missiles marks an escalation, said Behnam Ben Taleblu, a senior fellow at the Foundation for Defense of Democracies who specialises in Iran. The militias have typically used drones and rockets to attack.

Saturday’s ballistic missile attack on Al Asad injured four US service members, all of whom have returned to duty. One Iraqi security forces member was also injured.

Attacks against US facilities

Since the Israel-Hamas war began in early October there have been more than 151 attacks on US facilities in Syria and Iraq. According to the Pentagon, two attacks took place on Monday and included multiple rockets fired at US and coalition troops at Mission Support Site Euphrates in Syria and a single rocket fired at the Rumalyn Landing Zone in Syria. Neither attack resulted in casualties or damage.

The US struck back at the militia groups late last month, ordering a round of retaliatory strikes after three US service members were injured in a drone attack in northern Iraq. Kataib Hezbollah claimed credit for the attack, carried out by a one-way attack drone.

The US, in response, hit three sites, destroying facilities and likely killing a number of Kataib Hezbollah militants, according to the White House at the time.
