Plans in place for retaliatory strikes against Iran-backed militias: Live

President Joe Biden told reporters on Wednesday that he had decided on a response to the attacks, but did not want an escalation in fighting.

“I don’t think we need a wider war in the Middle East. That’s not what I’m looking for,” he said.

Meanwhile, US forces struck a Houthi drone base in Yemen in the early hours of Thursday morning after determining it presented an “imminent threat” to merchant and navy vessels in the region.

The Pentagon said in a statement that it had conducted strikes “against an Iranian-backed Houthi UAV ground control station and 10 Houthi one-way UAVs” at around 1.30am local time.

The Houthis have repeatedly attacked merchant and US navy ships in the region since November in retaliation for Israel’s war in Gaza, which is backed by the US.

The group’s spokesman said the attacks on vessels in one of the world’s busiest shipping routes would continue “until the aggression is stopped, and the siege is lifted on the people of Palestine in the Gaza Strip.”

Three US service personnel were killed and more than 40 were wounded last week after a drone hit a military outpost in Jordan known as Tower 22, on the border between Iraq and Syria. It marked the first time US soldiers have been killed by the attacks since the start of the Israel-Hamas war.

The White House determined that the attack was carried out by a loose alliance of Iran-backed militias in the region.

“We believe that the attack in Jordan was a plan resourced and facilitated by an umbrella group called the Islamic Resistance in Iraq, which contains multiple groups, including Kataib Hezbollah,” Mr Kirby said.

US secretary of defence Lloyd Austin said on Thursday that the military response to those deaths will be “multi-tiered”.

“Again, we have the ability to respond a number of times, depending on what the situation is,” he added.

When questioned by The Independent about whether the US classifies the fighting on multiple fronts against Iran-backed militias as a war, White House National Security Council spokesman John Kirby said he disagreed.

“There were attacks against our troops and facilities in Iraq and Syria well before the 7th of October — certainly in the last administration as well,” he said on Thursday. “And as for the Houthis, they can claim all they want that this is linked to Gaza, but two-thirds of the ships that they’re hitting have no connection to Israel whatsoever. So, it’s just not true. It’s a falsehood.”

US bases have been struck by more than 160 rocket and drone attacks by Iran-backed militias in Iraq and Syria since mid-October. US warships and international merchant vessels have also come under attack from Yemen’s Houthi rebels, who are also backed by Iran.

Concerns have been growing over the spread of violence across the Middle East linked to Israel’s war in Gaza, which was triggered by an attack by Hamas inside Israel in which around 1,200 people were killed and another 240 taken hostage. Israel’s war against Hamas, which is allied with Iran, has drawn in Iran’s allies from across the region — from Yemen’s Houthis to Lebanon’s Hezbollah. Israel’s war has killed more than 26,000 Palestinians, mostly women and children, according to the Palestinian health ministry.

The Biden administration has said repeatedly that it hoped to prevent a wider regional escalation as a result of the Israel-Hamas war, but the intervention of the Houthis and the killing of US soldiers has resulted in a series of military confrontations that resemble a low-level regional war. The US now regularly carries out strikes against the Houthis in Yemen, as well as Iran-backed militias in Iraq and Syria.

Defense Secretary Lloyd Austin said Thursday it’s time to further disable Iran-backed militias that have struck at U.S. forces and ships in the Middle East and the U.S. is preparing to take significant action in response to the deaths of three U.S. service members in Jordan.

For days the U.S. has hinted strikes are imminent. While the threat of retaliation for Sunday’s deaths has driven some militant groups to say they were stopping hostilities, as late as Thursday Yemen’s Houthi rebels were still attacking vessels and fired a ballistic missile at a Liberian-flagged container ship in the Red Sea.

“At this point, it’s time to take away even more capability than we’ve taken in the past,” Austin said Thursday in his first press conference since he was hospitalized on Jan. 1 due to complications from prostate cancer treatment.

Previous U.S. strikes have not deterred the attacks. Since the war between Israel and Hamas broke out in October, Iranian-backed militant groups have struck U.S. bases in Iraq and Syria at least 166 times with rockets, missiles and one-way attack drones, drawing about a half-dozen U.S. counterstrikes on militant facilities in both countries. The U.S. military also has carried out airstrikes targeting the Iran-backed Houthi rebels in Yemen.

US forces struck a Houthi drone base in Yemen in the early hours of Thursday morning after determining it presented an “imminent threat” to merchant and navy vessels in the region.

The Pentagon said in a statement that it had conducted strikes “against an Iranian-backed Houthi UAV ground control station and 10 Houthi one-way UAVs” at around 1.30am local time.

The strikes represent the latest in a series of US military actions against the Yemeni rebel group, which were launched in response to its attacks on ships in the Red Sea.

The Houthis have repeatedly attacked merchant and US navy ships in the region since November in retaliation for Israel’s war in Gaza, which is backed by the US.

The group’s spokesman said the attacks on vessels in one of the world’s busiest shipping routes would continue “until the aggression is stopped, and the siege is lifted on the people of Palestine in the Gaza Strip.”

The US is said to have approved plans to strike Iranian personnel and facilities in Iraq and Syria in response to a drone attack that killed three US soldiers in Jordan on Sunday.

US officials have characterised the response as a “campaign” that could last “weeks,” and will include both airstrikes and cyber attacks, according to NBC. It would target both the Iran-backed militias that carried out the deadly attack, and Iranian forces that support them in the region, officials told ABC separately.

The decision to attack Iranian personnel directly in Iraq and Syria marks a significant escalation in a volatile regional power struggle that pits the US against Iran and a network of allied militias in the Middle East.

US forces in the region have come under frequent attacks by Iran-backed militias opposed to the US presence in the region for years, but those attacks increased dramatically following Israel’s invasion of Gaza, and Washington’s unyielding support for the war.
