MOSCOW: Russia on Thursday suggested that Washington was quick to condemn the designation of Alexei Navalny鈥檚 groups as extremist because the jailed Kremlin critic was in fact working for the United States.

A Moscow court late on Wednesday ruled to designate Navalny鈥檚 regional offices and his Anti-Corruption Foundation (FBK) as 鈥渆xtremist,鈥� barring them from working in Russia.

The US State Department called the action 鈥減articularly disturbing鈥� and said it was part of a pattern of restricting fundamental rights in Russia.

In a radio interview on Thursday morning, Russian Foreign Ministry spokeswoman Maria Zakharova said the response showed the extent of US interference in Russia鈥檚 affairs.

鈥淐an you imagine seeing such an instant reaction from the State Department to a domestic or some other internal decision in another country?鈥� she said in the interview broadcast on YouTube and state radio.

鈥淭hen in a few hours they make a special statement. This means that they are politically involved in the story,鈥� she said, adding that Washington was thus exposing its 鈥渁gents.鈥�

鈥淭hey show such political zeal because it touches those whom they supervised, those whom they supported politically and in other ways,鈥� Zakharova said.

Prosecutors in April had requested that Navalny鈥檚 organizations be hit with the 鈥渆xtremist鈥� label, saying the group was plotting an uprising with support from the West.

Navalny鈥檚 network of regional offices had helped organize a smart voting strategy that urged voters to cast ballots for those most likely to defeat Kremlin-linked candidates.

Ahead of parliamentary elections in September 鈥� in which the deeply unpopular ruling United Russia party is expected to struggle 鈥� lawmakers passed legislation that bans members and sponsors of 鈥渆xtremist鈥� groups from running in the polls.
