Russia accuses Czechs of hysteria

Russia said on Thursday it would retaliate against any new punitive steps by the Czech Republic against Russian diplomatic staff as a spy row between the two countries threatened to escalate into a new round of expulsions. Russia ordered out 20 Czech diplomats on Sunday, after Prague expelled 18 Russians the day before.

On Wednesday the Czech Republic demanded that Moscow allow the return of all 20 staff to Moscow by Thursday or face further evictions of its diplomats from Prague.

At a time of acute tensions in Russia's relations with the West, the dispute has prompted NATO and the European Union to throw their support behind the Czech Republic, which is a member of both blocs. "Allies express deep concern over the destabilising actions Russia continues to carry out across the EuroAtlantic area, including on alliance territory, and stand in full solidarity with the Czech Republic," NATO's 30 allies said in a statement.

Kremlin spokesman Dmitry Peskov said Moscow took a negative view of Prague's "hysteria".In the past week, Moscow has also kicked out diplomats from Bulgaria, Poland and the United States in retaliation for expulsions of its own staff. President Vladimir Putin warned foreign powers in his state of the nation speech on Wednesday not to cross Russia's "red lines", saying Moscow would make them regret it. The Czechs say the loss of the 20 staff has effectively paralysed the functioning of their Moscow embassy, which is much smaller than the Russian mission in Prague. Maria Zakharova, spokeswoman for the Russian foreign ministry, accused Czech authorities of staging a "performance" and pledged Moscow would hit back with an "appropriate response" if Prague took any more actions against Russian diplomats.
