A new investigation into the poisoning of Russian opposition figure Alexei Navalny claims a team of intelligence agents with Russia’s Federal Security Service, or FSB, were involved in the act. Some of the agents specialized in toxins and nerve agents. They had reportedly been trailing Navalny for three years prior to his poisoning in August with the nerve agent Novichok. Navalny is still recovering in Berlin. The probe was conducted by journalists at a number of outlets, including CNN and Der Spiegel, as well as the online investigative website Bellingcat.
