Putin met with some of the mothers of the scores of children who were killed in Beslan when terrorists seized their school on the first day of lessons.
Putin promised the group there would be a thorough inquiry to answer any remaining questions about the hostage-taking crisis.
The episode ended when bombs exploded inside the school and Russian troops attacked the terrorists.
Relatives of the victims and survivors blame authorities for mishandling the crisis and say Russian assault troops were responsible for the high death toll.
