In Russia, relatives of victims of the 2004 Beslan school siege are claiming newly released video footage proves Russian authorities have covered up the circumstances around the bloody end to the crisis. Some 333 people, half of them children, were killed when Russian security forces stormed a school seized by Chechen separatists. Russia has claimed a bomb planted by the separatists caused the deaths. But relatives say new video from an investigator proves the theory that Russian troops fired grenades into the school before the bombs went off. The video shows large blasts and sustained gunfire, followed by rising smoke from the building.

Susanna Dudiyeva of the Beslan Mothers’ Committee: “We got the tape by chance. It was posted to us. For a long time we have been trying to determine and to clarify the nature of the very first explosion, and this tape proves that the explosions happened outside the building.”
