German Chancellor Angela Merkel gives a statement on September 2, 2020 at the Chancellery in Berlin after tests carried out by the German army on Russian opposition leader Alexei Navalny have provided "unequivocal evidence of a chemical nerve agent from the Novichok family." - The German government said that Russian opposition leader Alexei Navalny was poisoned with a Novichok nerve agent -- the same type of chemical used in Britain against ex-double agent Sergei Skripal, dramatically ramping up tensions with Moscow. Navalny, 44, fell ill after boarding a plane in Siberia last month. He was initially treated in a local hospital before being flown to Berlin for treatment. (Photo by Markus Schreiber / POOL / AFP)
