A leading Russian opposition figure Alexei Navalny was poisoned with a Novichok nerve agent in August 2020. He became ill and was taken to Germany for medical treatment, but has since mostly recovered. There is strong evidence that the Russian Federal Security Service (FSB) was responsible for the poisoning. In January 2021 Navalny returned to Russia and was immediately arrested. He has been convicted of multiple crimes, including parole violations and slandering a veteran. In these internationally criticized trials he has been sentenced to numerous years in prison.
