Joe Biden trips and falls during graduation ceremony
Joe Biden has tripped and fallen during a graduation ceremony at the US Air Force academy.
The American president, 80, was quickly helped up by three people, and walked back to his seat unassisted following the incident in Colorado.
As the leader was helped up, he pointed behind him, seeming to indicate what he tripped over.
White House communications director Ben LaBolt said Mr Biden was fine.
“There was a sandbag on stage while he was shaking hands,” he said on Twitter.
Mr Biden, who stood for much of the hours-long ceremony to shake hands with graduates, appeared to trip over something and fell to his knees towards the end as he handed out the last diploma.

At the presentation, he gave salutes to the blue-uniformed graduates.
In his address in Colorado Springs to more than 900 cadets, the US commander-in-chief warned graduates they will enter service in an increasingly unstable world, citing challenges from Russia and China.
The president is running for re-election in 2024.
