MOSCOW — Russia’s foreign minister says Moscow will expel the same number of diplomats from the nations that have expelled Russian diplomats over the poisoning of an ex-Russian spy in Britain.

Sergey Lavrov said U.S. Ambassador Jon Huntsman has been summoned to the Foreign Ministry on Thursday, where he was given notice that Russia is responding quid pro quo to the U.S. decision to order 60 Russian diplomats out.

Lavrov said Moscow will also retaliate to the U.S. decision to shut the Russian consulate in Seattle by closing the U.S. consulate in St. Petersburg.

Lavrov said the same approach will be applied to other nations that expelled Russian diplomats this week.

Two dozen countries, including the U.S., many EU nations and NATO, have ordered more than 150 Russian diplomats out this week in a show of solidarity with Britain.

In response, the United States says there’s “no justification” for Russia’s retaliatory move.

U.S. Ambassador to Russia Jon Huntsman said in a statement that it shows Moscow isn’t interested in dialogue with the United States about important matters.
