The UK will expel 23 Russian diplomats after Moscow refused to explain how a Russian‑made nerve agent was used on a former spy in Salisbury.
UK Prime Minister Theresa May said the diplomats, who have a week to leave, were identified as "undeclared intelligence officers".
She also revoked an invitation to Russia's foreign minister, and said the Royal Family would not attend the Fifa World Cup in Russia later this year.
Russia denies attempted murder and says it will respond appropriately.
A nerve agent called Novichok believed to be made by Russia is believed to have been used on former spy Sergei Skripal and his daughter, Yulia Skripal who remain critically ill in hospital.
