One of the two members of the National Guard who were shot in Washington DC on Wednesday has died, US President Donald Trump said
, BBC reports.
Sarah Beckstrom, 20, succumbed to her injuries, while the second National Guard member, 24-year-old Andrew Wolfe, "is fighting for his life", Trump said on Thursday evening.
Both were shot at close range near Farragut Square in downtown DC just after 14:00 EST (19:00 GMT) on Wednesday. Police have arrested one suspect in the shooting, Rahmanullah Lakanwal, a 29-year-old from Afghanistan.
The attack has prompted a range of announcements from the Trump administration aimed at curbing migration from Afghanistan and a number of other countries.
The two soldiers who were attacked had been deployed to the American capital as part of the Trump administration's efforts to crack down on what it sees as rampant crime in several US cities.
Trump confirmed Ms Beckstrom's death while on a Thanksgiving call with US service members.
"Sarah Beckstrom of West Virginia, one of the guardsmen that we're talking about, highly respected, young, magnificent person... She's just passed away. She's no longer with us," he said.
Trump later spoke to her parents, a White House official told BBC's US partner CBS News.
The US president previously said the attack underlined a major national security threat.
