3 US troops killed by Iranian-backed drone strike in Jordan, Biden says

(WASHINGTON) — Iranian-backed militants killed three American service members and wounded more than two dozen others in a drone attack in Jordan on Sunday, U.S. officials said, with President Joe Biden warning that the strike would be met with American retaliation.

The deaths were the first in the line of fire for U.S. troops since the start of the Israel-Hamas war in October, sparked by Hamas’ terror attack.

The U.S. has supported Israel against Hamas in Gaza but sought to prevent the conflict from enveloping the broader Middle East — as Iranian-backed militants have carried out a series of strikes in Iraq, Syria and Yemen in opposition to Israel’s campaign.

While the Biden administration has sought to prevent Israel’s war on Hamas from spreading, Pentagon officials have said that the deaths of American service members would elicit a strong response — a step that could draw the U.S. and other regional and international powers further into a mushrooming conflict.

“Have no doubt — we will hold all those responsible to account at a time and in a manner our choosing,” Biden said in a statement Sunday.

Secretary of Defense Lloyd Austin also lamented the attack, promising the U.S. would “respond at a time and place of our choosing.”

“The president and I will not tolerate attacks on American forces, and we will take all necessary actions to defend the United States, our troops, and our interests,” Austin said.

The three slain service members were not immediately identified, pending notification of their families, according to U.S. Central Command, which released a short statement on Sunday confirming the incident.

The strike occurred at the Tower 22 outpost, an administration official said.

CENTCOM said 25 troops were injured in the attack by a one-way drone, also known as a “suicide” drone.

Some of the injured service members received serious wounds from shrapnel and some were being screened for traumatic brain injuries, an official with the White House National Security Council said. The number of injured could change, this official said.

Biden was briefed multiple times in the hours after the strike and said in an initial statement on Sunday that the U.S. was “still gathering the facts” surrounding the “wholly unjust attack,” which he said occurred Saturday night.

The White House later clarified that the attack occurred early Sunday in Jordan, or late Saturday Eastern time.

The president on Sunday hailed the killed service members for being “unwavering in their bravery. Unflinching in their duty. Unbending in their commitment to our country.”

Located in the northeastern region of Jordan, the Tower 22 is a small outpost that supports operations across the border at the U.S. base at al-Tanf in Syria and contributes to the Pentagon’s advise-and-assist mission for the Jordanian military.

Iranian-backed militias have in recent months carried out more than a hundred attacks in the region, primarily on U.S. troops stationed in Iraq and Syria but also on American ships and interntaional commercial vessels in the Red Sea and the Gulf of Aden.

The strikes have wounded scores of American troops, including one who sustained a serious injury on Christmas Day in an attack on the Erbil Air Base.

Two Navy SEALS were also presumed dead after they were lost at sea during a mission that successfully intercepted a vessel carrying Iranian-made missile parts destined for Yemen.

U.S. forces began conducting retaliatory attacks on fighters in the Middle East in October, targeted strikes the Pentagon has consistently described as defensive measures intended to degrade the militias’ capabilities and deter them from escalating their attacks.

After months of attacks primarily targeting commercial vessels in the waters surrounding Yemen, the U.S. also launched a number of strikes against the country’s Houthi rebels in January.

U.S. officials initially expressed hope that carrying out operations in the two theaters would diminish the belligerent groups’ capabilities for further conflict, but the tit-for-tat exchanges with militants in Syria, Iraq and Yemen have instead steadily escalated.

That protracted pattern has fueled questions and concern about the broader military strategy.

Some lawmakers have also criticized the White House and Pentagon for not seeking authorization from Congress first, though the administration maintains it acted under existing legal authority to carry out such operations.

In the hours after the Jordan strike was confirmed, a growing number of members of Congress spoke out. Many of them offered condolences to the slain and wounded service members, and Republicans argued that the Biden administration had failed to adequately address Iran.

“We need a major reset of our Middle East policy to protect our national security interests and restore deterrence,” House Foreign Affairs Committee Chairman Michael McCaul said in a statement as House Speaker Mike Johnson called for “a crystal clear message across the globe that attacks on our troops will not be tolerated.”

In an interview taped last week with ABC News Chief Global Affairs Correspondent, Gen. CQ Brown Jr., the chairman of the Joint Chiefs of Staff, was asked if Americans being killed in the Middle East would impact his decision making.

He said the military was doing “everything we can to protect our forces” and noted the U.S. does not want “broader conflict” in the region — and that he doesn’t believe Iran wants war with the U.S., either.

“We don’t want to go down a path of greater escalation that drives to a much broader conflict within the region,” Brown said.

Before the start of the Israeli-Hamas war, U.S. forces in the Middle East experienced a two-year period of relative calm.

The last major attack to result in multiple American service members killed in action was the bombing outside of the Kabul airport in August of 2021, which claimed the lives of 13 U.S. troops and more than 180 Afghan citizens.
