Thousands of people are expected to gather in Beslan, in the Russian Caucasus republic of North Ossetia, to take part in three days of ceremonies and events to honor the victims.
On 1 September 2004, armed pro-Chechen separatist militants took hostage more than 1,100 pupils, parents, and teachers. The standoff ended two days later, on 3 September, when bombs exploded and Russian forces stormed the building.
At least 318 hostages, more than half of them children, were killed.
Radical Chechen field commander Shamil Basaev has claimed responsibility
for organizing the hostage taking.
Ahead of the anniversary, mothers of some of the victims have renewed accusations
that government authorities mishandled the crisis, in part leading to the high death toll.
They are due to meet with President Vladimir Putin at the Kremlin on 2 September.
