Putin Critic Navalny's Health Improving, German Hospital Says VOA News The health of Russian opposition leader Alexei Navalny is improving, and he now has been taken out of an induced coma and is responsive, the German hospital treating him said Monday. Navalny, a sharp critic of Russian President Vladimir Putin, was flown to Berlin on August 22, two days after falling ill on a domestic flight in Russia. German chemical weapons experts said tests showed he had been poisoned with a Soviet-era nerve agent from the Novichok group, a claim Russia has rejected. .
