Geiselnahme von Beslan
When armed Chechen extremists took more than 1,200 school children and adults hostage on September 1, 2004 in the Russian town of Beslan in North Ossetia, in what has become known as the Beslan school hostage crisis, 74-year-old Kanidis insisted on staying with his students, helped them survive and ultimately died to save their lives.
