UK National Security Adviser: Russia Expulsions Just First Step

As Russia was announcing who it would kick out over the mass expulsion of Russian spies over a nerve agent attack in Britain, the U.K.’s National Security Adviser Mark Sedwill was in Washington Thursday, conferring with Americans on next steps to check Moscow’s aggression.

“It’s mainly about a coherent approach by the Western alliance to a range of aggressive Russian behavior, of which the attack in Salisbury was just the latest, obviously a very acute example,” Sedwill said told a small group of reporters.
