Moscow is preparing a response to the Baltic states after the three countries expelled several Russian diplomats in solidarity with Prague, Maria Zakharova, spokeswoman of the Russian Foreign Ministry, told Russia’s TASS news agency.
"The authorities of these countries can have no doubts in our answer,” she said. "Their diplomats may already begin to figure out which of them will have to pack their things.”
The Russian Foreign Ministry is yet to issue a formal statement.
Earlier on Friday, Estonia, Latvia, and Lithuania announced they would be expelling Russian diplomats involved in espionage activities.

"My Latvian and Estonian colleagues have each expelled one [embassy] employee involved in espionage activities,” Lithuanian Foreign Minister Gabrielius Landsbergis said.
Vilnius will expel two Russian diplomats, he said without disclosing names. “They both had a diplomatic rank” and were involved in espionage, added Landsbergis.
Last week, the Czech Republic ordered 18 Russian diplomats, identified as secret agents, to leave the country and asked its partners to expel identified members of Russian intelligence services in an act of solidarity.
Citing an intelligence report, the Czech government has said that Russia's military intelligence agency, the GRU, orchestrated two explosions in 2014, one of which killed two people and caused extensive material damage.
