Deep scar of Beslan school massa

The pain of the Beslan school siege is still felt sharply in North Ossetia, as the Russian republic marks six years since the tragedy. More than 300 died in the massacre, led by Chechen militants who became the focus of Russia's terrorism crackdown. RT's Yegor Piskunov is in North Ossetia, where commemoration services will be held over the next three days.
