UK to expel 23 Russian diplomats

Theresa May said the diplomats, who have a week to leave, were identified as "undeclared intelligence officers".

The UK later told the UN Security Council that Russia had used "a weapon so horrific that it is banned in war" in a "peaceful" British city.

Russia denies attempted murder and says it will respond appropriately.

Mrs May 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.

It will also close two compounds used for Russian intelligence-gathering.

President Barack Obama had vowed action against Russia amid US accusations it directed hacks against the Democratic Party and Hillary Clinton's campaign.

Russia has denied any involvement and called the decision "ungrounded".

The US state department declared the 35 Russian diplomats from the Washington DC embassy and the consulate in San Francisco "persona non grata", and gave them and their families 72 hours to leave the US.
