The Bellingcat investigative journalism outlet has unmasked some of the Russian intelligence officers responsible for the attempted murder of journalist Alexei Navalny.

In August, Navalny was poisoned with a Novichok class nerve agent while traveling between Siberia and Moscow. But working with CNN, the Insider, and Der Spiegel, Bellingcat has documented who was behind the assassination attempt and how it was carried out. The joint investigation also corroborates and greatly expands on something I reported on Sept. 10: that Russia’s FSB intelligence service quickly proved its culpability for the attack when its officers engaged in panicked communications with Moscow after Navalny was transported alive to the hospital.
