Tensions are escalating to unprecedented levels between Great Britain and Russia, over the poisoning of a former spy and his daughter with a nerve agent attack in Salisbury, England last week.

Russia has been blamed for the attack, which has left Sergei Skripal and his daughter critically ill. Skripal, a former Russian intelligence officer, has been working for Britain.

Wednesday Great Britain Prime Minister Theresa May announced that 23 Russian diplomats are being expelled from the country, and has given them one week to get out.

In addition, May said, “There will be no attendance or indeed members of the Royal family at this summer’s World Cup in Russia.”

“We will freeze Russian state assets wherever we have the evidence that they may be used to threaten the life or property of UK nationals or resident,” May added.

The Hill noted that the decision puts U.S. President Trump to now take action as well.

The decision ramps up tensions between Moscow and London and may put pressure on the Trump administration to respond in backing one of the closest allies of the United States.

 President Trump told May in a phone call on Tuesday that the Kremlin needs to give Great Britain “unambiguous answers” about the attack, and that the U.S. was ready to provide assistance in their investigation.
The White House said the two leaders agreed that whoever carried out the attack needs to face consequences. 

Trump told reporters on Tuesday that he believes May’s assertion that Moscow was behind the attack.

“It sounds to me like it would be Russia based on all the evidence they have,” Trump said. “It sounds to me like they believe it was Russia and I would certainly take that finding as fact.”
