Russian opposition politician Alexei Navalny was poisoned with a Novichok nerve agent, Germany’s government says.
Toxicology tests had shown “unequivocal proof” of a chemical nerve agent from the Novichok group, it said.
Mr Navalny was airlifted to Berlin for treatment after falling ill during a flight in Russia’s Siberia region last month. He has been in a coma since.
His team say he was poisoned on the orders of President Vladimir Putin. The Kremlin has dismissed the allegation.
