Russia will host on June 3-5 an international forum on the ways to counter terrorist propaganda among the public, RIA Novosti reported.
The meeting under the patronage of the Russian President Dmitry Medvedev will bring together top security and law enforcement officials from 63 countries and the UN counter-terrorism bodies.
"The ideological expansion of terrorism, the radicalization of the public and continuous attempts to involve the population in extremist and terrorist activities pose the biggest threat at present," the Russian Federal Security Service (FSB) said in a statement prior to the meeting.
"The use of advanced information technologies, primarily the Internet, presents a challenge that demands an immediate and adequate response," the statement said.
The FSB called for further cooperation between national and international security bodies in a multilateral format to increase the effectiveness of the fight against global terrorism.
