NATO has taken a central role in the Navalny poisoning case by calling for a stronger and unified response by the Western defence alliance.

Secretary-General Jens Stoltenberg said on Friday that Russia has serious questions to answer over the use of Novichok, the poison used in the attack on the Russian dissident leader that left him in a coma.

“The use of such a weapon is horrific. Those responsible for the attack must be bought to justice,” Stoltenberg said. he called the attack on August 20 as a serious breach of international law that requires an international response, but did not speculate on what form that response could take.

Members of the European Parliament have also waded into the issue, with 100 members writing to EU Foreign Minister Josep Borrell asking for a unified EU response.

“We remain extremely sceptical that Russian authorities are fit and willing to investigate the real background of this crime.
“We all look back at a long history of Putin opponents and independent journalists attacked and/or murdered and Russian authorities failing to bring to justice the real perpetrators,” they said.
