Former Hamburg-cell member Squadron Leader Atif bin Mansour helped organise the 13th World Junior Men's Squash Championship in Pakistan in August 2004.
As you can see from a press release by the Mexican team (which finished twelfth - 2 places ahead of the US), Squadron Leader Mansour was on the Organizing Committee as communications director.
