NATO and 26 countries expelled over 140 Russian diplomats in March 2018 following the Salisbury nerve agent attack, signalling united condemnation and reducing Russia’s intelligence capabilities.
In March 2018, NATO expelled seven Russian diplomats and announced reductions of Russia's mission size at its Belgium headquarters, as a direct response to the Salisbury nerve agent poisoning of ex-spy Sergei Skripal and his daughter on March 4. In solidarity, 26 other countries, including EU and NATO members, expelled over 140 Russian diplomats in total, with the UK leading by expelling 23 envoys. The move aims to impose consequences on Russia and degrade its espionage operations in Europe. Russia denied involvement and condemned the expulsions, accusing the US of pressuring other countries and promising retaliatory measures. Not all EU countries expelled diplomats; neutral countries like Austria, Greece, and Portugal condemned the attack but chose not to expel. UK Foreign Secretary Boris Johnson praised the international response, expressing that the world had enough of Russia’s behavior while rejecting claims of a new Cold War. The expulsion measures also form part of broader diplomatic tensions surrounding the upcoming 2018 FIFA World Cup in Russia with some countries boycotting official attendance.
Confidence: High
The article explicitly details NATO and allied countries expelling Russian diplomats as retaliatory diplomatic actions against Russia following a hostile nerve agent attack attributed to Russia. Russia is identified as the aggressor, with direct hostile hybrid warfare implications in the diplomatic/espionage domain.
