World Squash Day is celebrating its 20th anniversary since its inaugural year, as the sporting community took to social media.

Celebrated every October 10, the event was launched by a group of squash friends following the September 11 terror attacks in New York City.

Many members of the New York squash community were killed, including Derek Sword, a former Scottish junior international.

Sword's former team-mate and 1999 world champion Peter Nicol, is the President of World Squash Day.

Nicol is also a three-time Commonwealth Games gold medallist.

Coinciding with World Mental Health Day, Scottish Squash encouraged athletes to take a "Sweaty Selfie" as part of their #SquashTheStigma campaign, as they look to improve awareness of mental health.

Scottish Minister for Public Health, Women's Health and Sport was one of those who supported the initiative. 

Top English women's singles player Sarah-Jane Perry visited the University of Birmingham to meet children with the Birmingham 2022 Commonwealth Games mascot.

Black Ball Squash Club in Cairo welcomed dozens of juniors who are set to be among the 750 players to compete at the Black Ball Championships.

English player Daryl Selby celebrated the day with his children, playing squash together with them.
