A UK university professor has died after falling 40ft-50ft (12m-15m) on to rocks on a hiking trail in the US.
Professor Alexei Likhtman, 44, of the University of Reading, lost his balance and fell on a section of the Appalachian Trail in Maryland, said local police.
Other hikers tried to save him, but he died about an hour later on Sunday.

His family has been informed of his death.
He was at Annapolis Rock on the long-distance trail.

A spokesman for Maryland Natural Resources Police said Prof Likhtman was in the US for a conference in Baltimore.

"People in the area immediately began first aid and called 911.
"Emergency personnel arrived and immediately began first aid, but the victim was pronounced deceased about noon.
"He was with a student of his and was taking photographs. He had a tripod with a camera on it, the camera fell and he fell. He was jumping from rock to rock when he tripped."
Prof Likhtman's body was transferred to the office of the chief medical officer in Baltimore for a post-mortem examination to be carried out.
According to his social media accounts, Prof Likhtman was originally from Moscow before moving to the UK to study and teach.
He worked as a lecturer at the University of Leeds between 1999 and 2007 before taking up a post of professor of mathematical physics at Reading, working in applied mathematics.
