Russia has declared one Hungarian diplomat persona non grata in response to the country's hostile move towards Moscow in connection with the poisoning of ex-Russian intelligence officer Sergei Skripal and his daughter on British soil.
On March 30, Russia announced expulsion of Western states' diplomats in tit-for-tat after the UK and a number of European countries, as well as the US, Canada and Australia expelled Russian diplomatic staff. However, the actions of four countries, including Montenegro, Belgium, Hungary and Georgia, were left unanswered by Moscow, as they announced the anti-Russian punitive measures at the last moment.
