Terrorism fighting-related international legislation consideration is very important in terms of Russian criminal law reforming. There are over 16 agreements (conventions and protocols) accepted by international comminty that provide most dangerous terroristic acts definitions. These crimes constitute threat for both international and national security. All the related international laws have to be considered and represented in national criminal law in terms of effective terrorism counteraction. International legislation serves as base for terrorist crimes responsibility allocation in Russian criminal law. However, international legislation analysis shows that the Criminal Code of the Russian Federation does not completely consider the abovementioned issues. According to parts 1, 2 of the Criminal Code of the Russian Federation, Russian criminal legislation is based on generally accepted international law priciples and rules. While 1973 Convention on the Prevention and Punishment of Crimes against Internationally Protected Persons, including Diplomatic Agents requires criminal responsibility for intentional murder, kidnapping or other attack upon the person or liberty of an internationally protected person, violent attack upon the official premises, the private accommodation or the means of transport of an internationally protected person or threat to commit any such attack; the Criminal Code of the Russian Federation (art. 360) only provides responsibility for attack upon internationally protected person, upon the official premises, the private accommodation or the means of transport of an internationally protected person etc. The author concludes that all the terrorist acts provided by international legislation should be completely verbatim incorporated in the Criminal Code of the Russian Federation as one Chapter.
