Russian diplomats expelled across US and Europe

The United States and its European allies are expelling dozens of Russian diplomats in a co-ordinated response to the poisoning of a former Russian spy in the UK.

It is said to be the largest collective expulsion of Russian intelligence officers in history.

Prime Minister Theresa May said 18 countries have aligned with the UK, expelling more than 100 diplomats.

Russia vowed to retaliate to the "provocative gesture".

Russia denies any role in the attack on Sergei Skripal and his daughter, Yulia, in Salisbury, southern England. The pair remain in a critical but stable condition in hospital.

EU leaders agreed last week it was highly likely Russia was behind the nerve-agent poisoning.

Mrs May said: "President Putin's regime is carrying out acts of aggression against our shared values and interests within our continent and beyond.

"And as a sovereign European democracy, the United Kingdom will stand shoulder to shoulder with the EU and with Nato to face down these threats together."

Foreign Secretary Boris Johnson also praised the "extraordinary international response" by the UK's allies.

The Russian foreign ministry said the moves demonstrated a continuation of a "confrontational path".

"It goes without saying that this unfriendly act by this group of countries will not go without notice and we will react to it," its statement said.

Who is expelling diplomats?

The UK announced it was expelling 23 Russian diplomats earlier this month.

Various countries announced they were making the same move in solidarity on Monday. These are:

• US: 60 diplomats
• EU countries: France (4); Germany (4); Poland (4); Czech Republic (3); Lithuania (3); Denmark (2); Netherlands (2); Italy (2); Estonia (1); Croatia (1); Finland (1); Latvia (1); Romania (1); Sweden (1)
• Ukraine: 13
• Canada: 4

Why are they doing it?

President of the European Council Donald Tusk said 14 EU states had decided to expel Russian diplomats as a direct result of a meeting, held last week, about the Salisbury poisoning.

"Additional measures, including further expulsions within this common EU framework are not to be excluded in the coming days and weeks," he said.

The US state department said in a statement: "On March 4, Russia used a military-grade nerve agent to attempt to murder a British citizen and his daughter in Salisbury.

"This attack on our Ally the United Kingdom put countless innocent lives at risk and resulted in serious injury to three people, including a police officer."

It called the attack an "outrageous violation of the Chemical Weapons Convention and breach of international law".

The US is expelling 48 envoys at the Russian embassy in Washington and 12 more at the UN in New York. It will also order the closure of the Russian consulate in Seattle.
