The projection of cranes on the building of 'Crocus' in memory of the deceased.

Anyone can take part in the 'Flying Cranes' campaign by folding a paper crane, drawing a bird, or creating their own version and sharing it on social networks.

The campaign was named after the song 'Cranes', performed by Muslim Magomayev - a ballad about soldiers who become birds after death. The concert hall where the tragedy occurred bears his name.
