Passersby in central Berlin shared their views, Thursday, on the German government’s announcement a day earlier that Russian opposition leader Alexei Navalny had been poisoned with a chemical nerve agent from the Novichok family. German Chancellor Angela Merkel has said Navalny was "the victim of a crime” and that "there are very difficult questions which only the Russian government can and must answer.” One passerby in the German capital called for Berlin to adopt a tougher diplomatic approach towards Moscow in the wake of the announcement. "Not only sanctions but rather no negotiations, not always to indulge, which has always been the German strategy, it has been the strategy till now, Germany has eased off. This topic upsets me a lot, it is now difficult with Russia. America and now Russia, Europe, it makes me really worried," stated Rose-Marie Mueller.
