Last week, several lawmakers of the State Duma (lower house of the parliament) appealed to the Russian Investigative Committee and Prosecutor General's Office, as well as to the justice authorities of Germany, the United States, Cyprus and France, requesting an investigation into the facts of organizing and financing terrorism.
"Following the consideration of the appeal of lawmakers of the State Duma ... concerning the need to investigate the organization, financing and conduct of terrorist acts by the United States, Ukraine and other Western countries directed against Russia, in the central office of the Investigative Committee has launched a probe into the matter," the Russian Investigative Committee said on Telegram.
The investigation will carefully study the submitted data and make a procedural decision on the mater, the statement read.
Russian authorities believe their plan was to flee to Ukraine, where the masterminds of the attack had arranged a safe haven for them. An investigation is under way.
