Moscow will take retaliatory measures against the Czech Republic following the expulsion of Russian diplomats in the country, Russia's Ministry of Foreign Affairs said on Sunday.

"We will take retaliatory measures that will force the authors of this provocation to fully understand their responsibility for destroying the foundation of normal ties between our countries," the ministry said in a statement.

The Czech Republic expelled 18 Russian embassy workers from the Russian Embassy in Prague, Czech Prime Minister Andrej Babis said Saturday.

According to local media reports, the move comes in response to evidence obtained by the country's security services suggesting Russia's involvement in two ammunition depot explosions in the Czech Republic in 2014 that killed two people.

Moscow responded to the accusations, saying they were unfounded and absurd.
