Сколько террактов было совершено в России в 2018 году?
Some newspapers described the attack as "Russia's Columbine", a reference to the 1999 US high school massacre. Steven Rosenberg said the attack should not be surprising as he noted there had already been five attacks in schools in Russia in 2018 where a number of children were injured. A "Telegraph" article also claimed there had been half a dozen school attacks in Russia in 2018, although claiming the previous incidents involved knives and traumatic pistols rather than high-powered firearms.
