NATO Secretary General Jens Stoltenberg has responded to Russian opposition leader Alexei Navalny's possible poisoning.
"Germany announced Alexey Navalny was victim of a Novichok attack. I utterly condemn the use of a military-grade nerve agent, which makes it even more urgent that Russia conducts full & transparent investigation. We’ll consult with Germany & all #NATO Allies on the implications," Stoltenberg tweeted.
