The Czech Republic is threatening to expel all Russian diplomats from Prague after accusations Russia was behind an explosion in an ammunition facility in 2014. 

Czech Prime Minister Andrej Babis describes the explosion as “an unprecedented terror attack on our territory.”

Foreign and Interior Minister Jan Hamacek is expected to summon the Russian Ambassador today to discuss further steps after 18 Russian diplomats, believed to be secret agents, were expelled from the country earlier this week.
