NATO on Friday called for an international probe into the poisoning of Russian opposition leader Alexei Navalny and demanded Moscow reveal its Novichok nerve agent programme to the global chemical weapons watchdog.

After an emergency meeting of NATO‘s ruling council, alliance chief Jens Stoltenberg said all countries were united in condemning the “horrific” attack on Navalny.

Germany, where Navalny is being treated, briefed the other 29 nations on the case and Stoltenberg said there was “proof beyond doubt” Novichok was used.
