Russia said on Monday it would halt the activities of its diplomatic mission to NATO after the Western military alliance expelled eight Russians saying they were spies.

Foreign Minister Sergei Lavrov also said staff at NATO’s military mission in Moscow would be stripped of their accreditation from Nov. 1, and the alliance’s information office in the Russian capital would be shuttered.

If NATO members have any urgent matters, they can contact our ambassador in Belgium on these questions, Mr. Lavrov told a news conference.

NATO said on Oct. 6 it had expelled eight members of Russia’s mission to the alliance who it said were “undeclared Russian intelligence officers”.

Moscow said at the time that the expulsions undermined hopes that relations with the U.S.-led alliance could normalise.

NATO is not interested in equitable dialogue and joint work, Mr. Lavrov said on Monday, announcing the closure of the Russian mission. If that’s the case, then we don’t see the need to keep pretending that changes in the foreseeable future are possible, he added.

NATO said on Monday it had taken note of Mr. Lavrov’s comments but had received no official communication on the issues raised.

The dispute marks the latest deterioration in East-West ties that are already at post-Cold War lows.

German Foreign Minister Heiko Maas said Russia no longer seemed willing to talk to the West.

It’s more than just regrettable, this decision taken in Moscow, he said. It will seriously damage the relationship, Mr. Mass concluded.
