Iran-backed groups have stepped up attempts to kill US forces in Iraq with an intense volley of ballistic missiles fired at Al Asad airbase in western Iraq.

The attack is the largest by Iran-backed militias against US forces yet.

“It is a huge escalation, involving perhaps 15-20 missiles,” said Joel Wing, a California-based expert who has been tracking violence in Iraq for 16 years.

“It seems like things are spiralling. There’s no way they’re firing ballistic missiles and not expecting casualties.”

Mr Wing told media the US will almost certainly be drawn into a lethal response, if only to deter further attacks. One option for the US could be trying to kill a militia commander in a targeted strike.

A range of militias backed by Tehran operate in Iraq, most under the umbrella of the Popular Mobilisation Forces. They have stepped up their attacks on US forces in the country since the outbreak of the Israel-Gaza war and the related rise in regional tensions between Iran and its proxy groups and the US and Israel.

While the joint Iraqi-US operated Al Asad airbase has been hit with ballistic missiles before – Iran fired around 12 at the base in early 2020 – this latest attack is the largest by Iran-backed militia groups within Iraq.

Militias launched smaller salvos of one or two ballistic missiles at US forces at the end of last year but have mostly used much smaller, inaccurate rockets and small but deadly drones.

The escalation is part of the militias’ campaign to pressure the US to leave Iraq. There are about 2,500 American military trainers in the country under the International Coalition against ISIS.

Iraqi Prime Minister Mohammed Shia Al Sudani, who relies on Iran-backed militias and parties for support, has criticised militias for attacking coalition troops on Iraqi territory, but has upped his calls for US forces to leave the country as the conflict escalates.

Mr Al Sudani has also fiercely condemned US counter strikes against the militias as a “violation of sovereignty”.

The drones used by the militias, such as the Iran-made Shahed-136, carry up to 50kg of explosives, compared to ballistic missiles – used in Saturday’s attack – that can carry several hundred kilograms, potentially levelling entire buildings.

Centcom, the US headquarters in the Middle East, said some soldiers were “undergoing evaluation for traumatic brain injuries,” after Saturday’s attack, and that one Iraqi was seriously wounded.

After Iran’s 2020 missile attack on Al Asad, as many as 100 US soldiers sheltering in bunkers suffered concussive injuries from the missile strikes, each detonating up to 500kg of explosives and sending shock waves through concrete shelters.

The US said Patriot missile interceptors shot down a number of the missiles in Sunday’s attack, which also involved rockets flying at lower altitudes, possibly in an attempt to overwhelm air defences.

Iran has supplied the PMF militias with ballistic missiles smuggled from Iran, part of an effort to transfer the weapons to Syria.

In November, the Islamic Resistance in Iraq, which encompasses Kataib Hezbollah and a smaller group, Harakat Hezbollah Al Nujaba, released an image of what it claimed was a new ballistic missile, the Al Aqsa.
