sentences:  According to a report by the Russian human rights organization Memorial who had analyzed the television footage of the aftermath, an explosion of "one or several compact powerful explosive mechanisms" at ground level in this case is out of the question, as all the vertical elements in the rows of stalls remained standing, while the horizontal ones (tents and overhead covers) were destroyed and broken.In addition, those who were not protected by overhead cover received multiple fragmentation wounds, and the foreground showed the characteristic traces of cassette (cluster) ammunition of so-called "ball bombs" (munitions used in the "Tochka" missile warheads and intended for destruction of non-protected live forces in large areas).Finally, apparent fragments of "enormous" ground-to-ground missiles and cluster sub-munition canisters were found at the scene (as reported by Babitsky).
