The Prosecutor General's Office sent inquiries to the United States, Germany, France and Cyprus about terrorist attacks against Russia. The department considered appeals from State Duma deputies Andrei Krasov, Nikolai Kharitonov, Yana Lantratova and public figures Alexander Dugin and Andrei Derkach.

Earlier it was reported that the Investigative Committee began an investigation after a request to investigate the involvement of Ukraine, the U.S. and other Western countries in the terrorist attacks.
