Joe Biden has said the US “shall respond” after three American troops were killed and dozens more were injured in a drone strike on Saturday night in northeast Jordan near the Syrian border.
Mr Biden, who was travelling in South Carolina on Sunday, asked for a moment of silence during an appearance at a Baptist church’s banquet hall.
“We had a tough day last night in the Middle East. We lost three brave souls in an attack on one of our bases,” he said. After the moment of silence, Mr Biden added, “and we shall respond”.
As the risk of escalation in the region continues, US officials are working to conclusively identify the group responsible for the attack, but they have ascertained one of several Iranian-backed groups was behind it.
So far one umbrella group, the Islamic Resistance in Iraq, an Iranian-backed militia operating in Iraq and Syria has claimed responsibility for the “suicide” drone attack.

Mr Biden has said in a written statement that the US “will hold all those responsible to account at a time and in a manner (of) our choosing”.
Defence secretary Lloyd Austin said “we will take all necessary actions to defend the United States, our troops, and our interests”.
Mr Biden’s rival for the White House this year, Donald Trump, said: “This brazen attack on the United States is yet another horrific and tragic consequence of Joe Biden’s weakness and surrender.”
UK Foreign Secretary David Cameron said: “We strongly condemn attacks by Iran-aligned militia groups against US forces. We continue to urge Iran to de-escalate in the region.
“Our thoughts are with those US personnel who have lost their lives and all those who have sustained injuries, as well as their families.”
Iran-backed fighters in east Syria have begun evacuating their posts, fearing US airstrikes, according to Omar Abu Layla, a Europe-based activist who heads the Deir Ezzor 24 media outlet.
According to a US official, the number of troops wounded in the attack by a one-way attack drone may grow.
The official said a large drone struck the base, identified as an installation known as Tower 22.
What is Tower 22?
Tower 22 holds a strategically important location in Jordan, at the most northeastern point where the country’s borders meet Syria and Iraq.
Little is information about the base is publicly known, but it includes logistics support and there are 350 US Army and Air Force troops stationed on site.
Tower 22 is near al-Tanf garrison, which is located across the border in Syria, and which houses a small number of American troops.
Tanf had been key in the fight against Islamic State and has assumed a role as part of a US strategy to contain Iran’s military build-up in eastern Syria.
Tower 22 is located close enough to American troops at Tanf that it could potentially help support them, while also potentially countering Iran-backed militants in the area and allowing troops to keep an eye on remnants of Islamic State in the region.
It is not currently clear what type of weaponry is kept at the base, what air defences are used, nor what exactly went wrong.
It is along the Syrian border with Jordan and largely used by troops involved in the advise-and-assist mission for Jordanian forces.
The small installation, which Jordan does not publicly disclose, includes US engineering, aviation, logistics and security troops.
The US military base at al-Tanf in Syria is just 12 miles north of Tower 22.
The Jordanian installation provides a critical logistical hub for US forces in Syria, including those at al-Tanf, which is near the intersection of the Iraq, Syria and Jordan borders.

Jordanian state television quoted Muhannad Mubaidin, a government spokesman, as saying the attack happened across the border in Syria.
US troops have long used Jordan, a kingdom bordering Iraq, Israel, the Palestinian territory of the West Bank, Saudi Arabia and Syria, as a basing point.
US Central Command put the total casualties at three killed and 34 injured.
Those killed were sleeping in a tent and some of those injured have been evacuated from the country.
Some 3,000 American troops typically are stationed in Jordan.

Pressure mounts on Joe Biden
Since the war in Gaza began on 7 October, Iranian-backed militias have struck American military installations in Iraq more than 60 times and in Syria more than 90 times, with a mix of drones, rockets, mortars and ballistic missiles.
The attack on Sunday was the first targeting US troops in Jordan during the Israel-Hamas war and the first to kill Americans.
Scores of US personnel have been wounded, including some with traumatic brain injuries, during the attacks.
The militias have said their strikes are in retaliation for Washington’s support for Israel and that they aim to push US forces out of the region.

The US in recent months has hit targets in Iraq, Syria and Yemen to respond to attacks on American forces in the region and to deter Iranian-backed Houthi rebels from continuing to threaten commercial shipping in the Red Sea.
Syria is still in the midst of a civil war and long has been a launch pad for Iranian-backed forces there, including the Lebanese militia Hezbollah. Iraq has multiple Iranian-backed Shiite militias operating there as well.
Jordan, a staunch Western ally and a crucial power in Jerusalem for its oversight of holy sites there, is suspected of launching airstrikes in Syria to disrupt drug smugglers, including one that killed nine people earlier this month.
A second child in Texas with measles has died as the outbreak of the childhood disease reached nearly 500 cases in the state, officials have said.
The unvaccinated schoolgirl, who had no underlying health conditions, died on Thursday in hospital from measles pulmonary failure, the Texas Department of State Health Services said.
She was being treated for complications from the illness, a spokesperson for University Medical Center Children’s Hospital in Lubbock said in an email.

The girl was recently diagnosed with the viral disease, NBC, Sky’s US partner said, quoting from the hospital’s statement issued on Sunday.
Two children have now died in Texas since an outbreak of measles in late January in Gaines County, where the vaccination rate is about 82%, below the 95% believed to ensure those who cannot be vaccinated are safe.
An adult in New Mexico is also suspected of having died from measles, NBC said, calling the deaths the first from the disease in the US for 10 years.
US President Donald Trump, speaking to reporters on Air Force One on Sunday, said that, if the outbreak continues, his administration will “have to take action very strongly”.
How to avoid spreading or catching measles
Measles is spread when an infected person breathes, coughs or sneezes.
A rash usually appears a few days after the cold-like symptoms. The rash starts on the face and behind the ears before spreading to the rest of the body.
A person is infectious from when they first have symptoms (around four days before the rash appears) until four days after they get the rash.
There are things people can do to reduce the risk of spreading or catching measles.
Do: Wash hands often with soap and warm water. Use tissues when coughing or sneezing. Throw used tissues in the bin.
Don’t: Do not share cutlery, cups, towels, clothes, or bedding.
Information from NHS website
US Health and Human Services Secretary Robert F Kennedy Jr, identified the child as eight-year-old Daisy Hildebrand and said he visited Texas on Sunday to comfort the child’s family.
Pictures were published of him at the girl’s funeral in Seminole, northwest Texas.

In a post on X, Mr Kennedy, a vaccine sceptic who says it should be a personal choice, said vaccines are nonetheless the best protection against the illness.
He said the MMR (measles, mumps, rubella) vaccine is “the most effective way to prevent the spread of measles”, confirming that, as of Sunday, there were 642 confirmed cases of measles in the US, 499 of those in Texas.

March: Why are measles cases so high?
The Texas Department of State Health Services said, as of Friday, 481 cases of measles had been confirmed, a rise of 14% in a week.
They include six infants and toddlers at a Lubbock day care centre that tested positive in the past two weeks.
Two of those children are among 56 people who have been treated in hospital for measles in the area since the outbreak started, NBC said, quoting health officials.
Measles is one of the most contagious viruses for humans. In serious cases, infections can cause complications including pneumonia, encephalitis, dehydration and blindness.
The Texas Department of State Health Services described it as a “highly contagious viral infection, which can cause life-threatening illness to anyone who is not vaccinated”.
Early symptoms can include a fever, cough and a runny nose, developing into a red-brown rash and high temperature.
Until five weeks ago, Arturo Suarez was a professional singer, performing in the United States as he waited for his asylum claim to be processed.
Originally from Venezuela, he had entered the US through proper, legal channels.
But he is now imprisoned in a notorious jail in El Salvador, sent there by the Trump administration, despite seemingly never having faced trial or committed any crime. The White House claims he is a gang member but has not provided evidence to support this allegation.
His brother, Nelson Suarez, told Sky News he believes his brother’s only “crime” is being Venezuelan and having tattoos.

“He is not a gang member,” Nelson says, adamantly, “I’ve come to the conclusion that it has to be because of the tattoos. If you don’t have a criminal record, you haven’t committed any crime in the United States, what other reason could there be? Because you’re Venezuelan?”
Arturo, 34, was recording a music video inside a house in March when he was arrested by immigration agents.
He was first taken to a deportation centre in El Paso, Texas, and then, it appears, put on to a military flight to El Salvador.

His family have not heard from him since. Lawyers and immigrant rights groups have been unable to make contact with any of the more than 200 Venezuelan men sent to the CECOT prison, which holds members of the MS-13 and Tren de Aragua gangs.
Tattoo clue to Arturo Suarez’s whereabouts
Nelson learned his brother is – most likely – in CECOT only because of a photograph he spotted on a news website of a group of inmates, with their hands and feet cuffed, heads shaved and bodies shackled together.

“You can see the hummingbird tattoo on his neck,” Nelson says, pointing to the picture. He says Arturo wanted a hummingbird in memory of their late mother. Arturo has 33 tattoos in total, including a piano, poems and verses from the Bible.
It could be that one, or more, of those tattoos landed him at the centre of President Trump’s anti-immigration showpiece. Nelson shows me documents which indicate that Arturo did not have a criminal record in Venezuela, Chile, Colombia or the United States, the four countries he has lived in.
Sky News contacted the White House, the Department of Homeland Security (DHS), and Immigration and Customs Enforcement (ICE) for a response to Arturo’s case but have not heard back.
In March, Donald Trump signed the Alien Enemies Act, a law from 1798 which has been invoked just three times before, in wartime.
It allows the president to detain and deport immigrants living legally in the US if they are from countries deemed “enemies” of the government. In this instance, Mr Trump claimed the Venezuelan gang Tren de Aragua had “infiltrated the United States” and was “conducting irregular warfare”.

Gang symbol tattoos
Immigration officials have centred on certain tattoos being gang symbols. Immigration officers were provided with a document called the “Alien Enemy Validation Guide”, according to a court filing from the American Civil Liberties Union. The document provides a point-based system to determine if an immigrant in custody “may be validated” as a gang member.
Migrants who score six points and higher may be designated as members of the Tren de Aragua gang, according to the document. Tattoos which fall under a “symbolism” category score four points and social media posts “displaying” gang symbols are two points. Tattoos considered suspicious, according to the document, include crowns, stars and the Michael Jordan Jumpman logo.
Jerce Reyes Barrios’s story
Another of the men sent to CECOT prison is 36-year-old Jerce Reyes Barrios, who fled Venezuela last year after marching in anti-government protests. He is a former footballer and football coach.
His lawyer, Linette Tobin, told Sky News that Reyes Barrios entered the US legally after waiting in Mexico for four months for an immigration appointment and then presenting himself at the border.
Image: Jerce Reyes Barrios
She says he was detained in a maximum security prison in the US while awaiting his asylum appointment. But before that appointment happened, he was flown to the El Salvador prison.
Ms Tobin says the DHS deported Reyes Barrios because they designated him a Tren De Aragua gang member based on two pieces of evidence.
The first, she says, is a tattoo of the Real Madrid football team logo surrounded by rosary beads. She has since obtained a declaration from the tattoo artist stating that Reyes Barrios just wanted an image which depicted his favourite team.

The second piece of evidence, she says, is a photograph, which she shows me, of Reyes Barrios in a hot tub with friends when he was a college student 13 years ago.
He is making a gesture which could be interpreted as “rock and roll”, but which she says has been interpreted as a gang symbol.

Distraught family in despair
Reyes Barrios has no criminal record in his home country. “I’ve never known anything like this,” Ms Tobin says.
“My client was deported to a third country and we have no way of getting in touch with him. His family are distraught and in despair, they cry a lot, not knowing what is going on with him. We want him returned to the United States to have a hearing and due process.”
Ms Tobin says she and other lawyers representing men sent to the El Salvador prison are trying to establish a UN working group on enforced disappearances to do a wellness check on them because the prison is completely “incommunicado”.

17 March: US migrants deported to El Salvador
Sky News contacted the DHS for comment about Reyes Barrios’s case but did not receive a response. The DHS previously issued a statement declaring that “DHS intelligence assessments go well beyond just gang-affiliated tattoos. This man’s own social media indicates he is a member of Tren de Aragua”.
Reyes Barrios has an immigration hearing scheduled for 17 April, Ms Tobin says, which the Trump administration is trying to dismiss on the grounds that he is not in the US anymore.
In the meantime, children he used to coach football for in his hometown of Machiques in Venezuela have been holding a prayer vigil for him and calling for his release.

“Do not come to our country illegally,” she said, “you will be removed, and you will be prosecuted.” Donald Trump had promised during his election campaign to clamp down on immigration, railing against undocumented immigrants and claiming immigrants are “poisoning the blood of our country”.
I ask Arturo Suarez’s brother, Nelson, how he felt watching Ms Noem posing in the prison, knowing that his brother might be close by.
“I feel bad,” he says, “I feel horrible, because in those images we only see criminals. With my brother, I feel it is more a political issue. They needed numbers, they said, these are the numbers, and now, let’s throw them to the lions.”

Kilmar Abrego Garcia’s story
The Trump administration has admitted that at least one man sent to the El Salvador jail was sent by “administrative error”. Kilmar Abrego Garcia, who was living in Maryland, was sent to CECOT despite a judge’s earlier ruling in 2019 that granted him legal protection to stay in the US.
The White House has alleged Garcia is an MS-13 gang member, but his lawyers argued there is no evidence to prove this.
A federal judge has ordered Garcia must be returned to the US by Monday 7 April. In a post on X, White House deputy chief of staff Stephen Miller referred to the judge as a “Marxist”, who “now thinks she’s president of El Salvador”.
White House press secretary Karoline Leavitt said: “We suggest the judge contact President Bukele because we are unaware of the judge having jurisdiction or authority over the country of El Salvador.”
International stock markets have fallen dramatically overnight amid fears of a global trade war following Donald Trump’s sweeping tariffs, which he called “medicine”.
Japan’s Nikkei 225 stock index dived nearly 8%, Australia’s S&P/ASX 200 fell more than 6%, and South Korea’s Kospi lost 4.4%.
Meanwhile US stock market futures signalled further weaknesses, with the future for the S&P 500 losing 4.2% and the Dow Jones Industrial Average falling 3.5%, while the future for the Nasdaq lost 5.3%.
Mr Trump warned foreign governments would have to pay “a lot of money” to lift his tariffs, which he described as “medicine”.
“I don’t want anything to go down. But sometimes you have to take medicine to fix something,” he said on Air Force One.

The US president said he had spoken to leaders from Europe and Asia over the weekend who had hoped to convince him to lower the tariffs, which are due to come into effect this week.
“I spoke to a lot of leaders, European, Asian, from all over the world,” Mr Trump said. “They’re dying to make a deal. And I said, we’re not going to have deficits with your country. We’re not going to do that because to me, a deficit is a loss. We’re going to have surpluses or, at worst, going to be breaking even.”
Mr Trump, who spent much of the weekend playing golf in Florida, posted on his Truth Social platform: “WE WILL WIN. HANG TOUGH, it won’t be easy.”

Trump’s tariffs: What you need to know
On Saturday, US customs agents began collecting Mr Trump’s unilateral 10% tariffs on all imports from many countries.
Higher “reciprocal” tariffs of between 11% and 50% on individual countries are due to come into effect on Wednesday.
Mr Trump’s tariff announcements have jolted economies around the world, triggering retaliatory levies from China and sparking fears of a global trade war and recession.
Investors and political leaders have struggled to determine whether the tariffs are here to stay, or are part of a permanent new regime or a negotiating tactic to win concessions from other countries.

‘Nothing off the table’ over tariffs
Meanwhile, KPMG warned US tariffs on UK exports could see GDP growth fall to 0.8% in 2025 and 2026.
The accountancy firm said higher tariffs on specific categories, such as cars, aluminium and steel, would more than offset the exemption on pharmaceutical exports, leaving the effective tariffs imposed on UK exports at around 12%.
Yael Selfin, chief economist at KPMG UK, said: “Given the economic impact that tariffs would cause, there is a strong incentive to seek a negotiated settlement that diminishes the need for tariffs. The UK automotive manufacturing sector is particularly exposed given the complex supply chains of some producers.”
