A group of Trump supporters has begun building the first privately constructed US-Mexico border wall after a crowd-funding campaign.
US military veteran Brian Kolfage posted a picture of the steel fence going up in the state of New Mexico.
He said it was being erected with more than $22m (£17m) in donations he raised through an online campaign last year.
The fundraiser was launched as Congress refused President Donald Trump funding for his signature campaign promise.
Mr Kolfage, an Air Force veteran, triple amputee and Purple Heart recipient, tweeted a series of videos and images showing the new barrier on Sunday.
"WE MADE HISTORY! The first crowdsource funded international border wall!" Mr Kolfage wrote on Twitter.
The barrier is being built through his nonprofit organisation WeBuildtheWall Inc, which he set up after organising a GoFundMe campaign in December entitled We The People Will Fund The Wall.
Former White House chief strategist Steve Bannon is chairman of WeBuildtheWall's advisory board.
