These are all the countries that are expelling Russian diplomats

It’s the biggest collective expulsion of alleged Russian intelligence officers in history, according to British Prime Minister Theresa May.

Diplomats are being kicked out of more than 20 countries – including 18 European Union states, the United States and Canada – in a coordinated effort that represents a significant diplomatic victory for the UK, which blames Russia in the March 4 poisoning of former spy Sergei Skripal and his daughter, Yulia, in Salisbury, England.

The UK has already expelled 23 Russian diplomats. Moscow retaliated by sending the same number of UK diplomats back, and by shuttering British cultural institutions in the country.

Here’s what each country is doing:

European Union nations

Belgium: A Foreign Ministry spokesman told CNN the country would expel one diplomat to show solidarity with the UK.

Croatia: Prime Minister Andrej Plenkovic said Croatia would expel one diplomat.

Czech Republic: The Czech Republic will expel three diplomats, Prime Minister Andrej Babis and Foreign Minister Martin Stropnicky announced at a press conference. The Czech Foreign Ministry tweeted that it declared the diplomats “personae non gratae.”
