 Russia's Investigative Committee initially classified the attack as terrorism but later changed it to mass murder.After the first reports of an alleged terrorist attack in Kerch, many Russian politicians and mass media suggested that the events were the activities of "Ukrainian saboteurs" and that the Ukrainian government was responsible, but changed their views after more information emerged, while others questioned whether Roslyakov was sufficiently checked before being allowed to purchase a gun and ammunition, which Roslyakov legally did.Sergei Mikhailovich Smirnov, deputy head of Russia's Federal Security Service (FSB), said the security services needed to have greater control over the Internet.
