British Foreign Secretary Boris Johnson said the Western action against scores of Russian diplomats in the United States and Europe was the biggest such expulsion of Russian spies ever.

"Today's extraordinary international response by our allies stands in history as the largest collective expulsion of Russian intelligence officers ever and will help defend our shared security," Johnson said on Twitter.

"Russia cannot break international rules with impunity."
