The US has suspended all immigration requests for Afghan nationals after two National Guard soldiers were shot near the White House.
It comes after the suspect of Wednesday’s shooting, which US President Trump labelled as an “act of terror”, was identified by the Department of Homeland Security as Afghan national Rahmanullah Lakanwal. It is understood he arrived in the US in September 2021.
The two soldiers, who were part of a militarized law enforcement mission ordered by Trump months ago, were hospitalised in critical condition.
The suspect was wounded in an exchange of gunfire before he was arrested, US officials said.
Led by the FBI’s Joint Terrorism Task Force, investigators are working to understand what motivated the shooting, carried out just a few blocks from the White House in what officials called an "ambush" attack on Thanksgiving eve.
Tens of thousands of Afghan nationals entered the US under special immigration protections following the US withdrawal from the country in 2021, under former president Joe Biden.
The 29-year-old suspect is understood to have entered the country under the Operation Allies Welcome programme.
An official told the BBC’s US news partner CBS that he applied for asylum in 2024 and his application was granted earlier this year.
Trump, who was at his resort in Florida at the time of the attack, released a prerecorded video statement late on Wednesday calling the shooting "an act of evil, an act of hatred and an act of terror."
He said his administration would "re-examine" all Afghans who came to the US during Joe Biden's presidency.
The US Citizenship and Immigration Services agency later said that it has halted processing of all immigration requests relating to Afghan nationals indefinitely, "pending further review of security and vetting protocols."
NBC News, citing an interview with an unnamed relative of the suspect, reported early on Thursday that Lakanwal served in the Afghan army for 10 years alongside US Special Forces troops and was stationed in Kandahar for part of that time.
The relative also said Lakanwal was working for online retail giant Amazon.com the last time they spoke several months ago, according to NBC News.
The DHS did not include other details of his immigration record, but a Trump administration official who spoke on condition of anonymity said Lakanwal applied for asylum in December 2024 and was approved on April 23 of this year, three months after Trump took office.
Lakanwal, who resided in Washington state, had no known criminal history, the official said.
The shooting unfolded at midday outside a subway station in a bustling commercial area within a few blocks of the White House. Secret Service agents placed the presidential mansion under a security lockdown immediately after the shooting as a precaution.
In response, Defense Secretary Pete Hegseth said the president had asked to send another 500 National Guard troops to join the more than 2,000 Guard soldiers previously mobilized in the nation's capital.
Vice President JD Vance, who was in Kentucky on Wednesday, said in a post on X that the shooting proved that the Trump administration's immigration policy was justified.
"We must redouble our efforts to deport people with no right to be in our country," he said.
Critics of the Trump administration's immigration policy say it has employed illegally harsh tactics and swept up immigrants indiscriminately, including some with no criminal history and others here legally.
Washington Mayor Muriel Bowser, who has clashed openly with Trump over the deployment of Guard troops in her city, told reporters hours after the incident, "this is a targeted shooting."
At the same news briefing, Jeff Carroll, executive assistant chief of the Washington Metropolitan Police Department, said the two Guard soldiers were "ambushed" and that the known assailant appeared to have acted alone.
The two soldiers, members of the West Virginia National Guard, were on a "high-visibility patrol" outside the entrance to a subway station when the suspect "came around the corner," drew a weapon and immediately fired at the pair, Carroll said.
After an exchange of gunfire, other National Guard troops subdued the suspect, he said.
Trump said in August he was ordering the National Guard deployment to fight crime in a city he said had become unsafe, despite objections from District of Columbia officials who challenged the move in court as an infringement on local government control.
Wednesday's shooting came five days after a federal judge issued a ruling to temporarily block National Guard troops from performing law enforcement duties in the district without the mayor's approval, but the judge paused the effect of her order until December to allow an appeal from the Trump administration.
Trump, a Republican, has deployed troops in several other Democratic-led cities - Los Angeles, Chicago, Portland, Oregon, and Memphis, Tennessee - to combat what he has described as lawlessness and violent unrest over his crackdown on illegal immigration.
Democratic leaders of those cities have accused Trump of manufacturing pretexts for militarised shows of force to punish political foes.
