The Games have been used an opportunity to mourn the Munich 11 at every competition since 1995. More than 3,000 young Jews from around the world, including a British contingent, will be at this summer's competition, which is dedicated to the memory of the 11 athletes who were brutally murdered by Palestinian terrorists 40 years ago.
