Israeli President Reuven Rivlin and dozens of world leaders attending this week's Fifth World Holocaust Forum in Jerusalem will take part in the online Holocaust education project known as "Eva Stories," which tells the story of a Hungarian girl through Instagram.

In the project, dozens of Instagram video posts, in a special format known as "stories," show a cast in costumes and locations acting out passages from the diary of Eva Heyman, a 13-year-old Hungarian deported to her death in the Auschwitz concentration camp in 1944.

The leaders will be active participants in the stories, sending the digital character online messages. This, organizers say, will help make the project even more widespread and help combat anti-Semitism. Their messages, which will address Eva and contemporary children, will include the pledge of "Never Again."
