BERLIN—A critic of President Vladimir Putin who fell into a coma in Russia and is being treated in Berlin was attacked with a Soviet-style Novichok nerve agent, a German government spokesman said on Wednesday.
Tests conducted at a German military laboratory produced “unequivocal evidence” that Alexei Navalny, Russia’s most prominent opposition figure, had been poisoned with Novichok, Steffen Seibert said in an emailed statement.
