Following British Prime Minister Theresa May’s condemnation of Russia over the nerve agent attack against a man and his daughter in England recently, U.N. Ambassador Nikki Haley issued a statement at the United Nations on Wednesday standing in support of Britain.

Earlier Wednesday, May announced that all 23 Russian diplomats were being expelled from the country, as a result of the poisonous attack against a former Russian spy, Sergei Skripal, and his daughter, which has left both critically ill.

“Let me make one thing clear from the very beginning… the United States stands in absolute solidarity with Great Britain,” Haley said Wednesday at the United Nations.

“The United States believes that Russia is responsible for the attack on two people in the United Kingdom using a military-grade nerve agent,” Haley stated.

“No two nations enjoy a stronger bond than that of the United States and the United Kingdom. Ours is truly a special relationship. When our friends in Great Britain face a challenge, the United States will always be there for them. Always.”

“Alone, Russia’s crime is worthy of this council’s action, but this is not an isolated incident,” Haley said, noting that it is part of an alarming increase in the use of chemical weapons, and referencing the assassination of Kim Jong-Un’s brother, along with gas attacks on Syrians.

“A growing concern is all of this dangerous and destabilizing activity is Russia,” she said.

“If Russia cooperated, by turning over all information related to this nerve agent, we would stop talking about them,” Haley said, adding, “We take no pleasure in having to constantly criticize Russia, but we need Russia to stop giving us so many reasons to do so.”

“Russia must fully cooperate with the U.K.’s investigation and come clean about its own chemical weapons program,” Haley challenged.

“If we don’t take immediate concrete measures to address this now, Salisbury will not be the last place we see chemical weapons used. They could be used here in New York or in cities of any country that sits on this council.”

“This is a defining moment. Time and time again member states say they oppose the use of chemical weapons under any circumstances. Now one member stands accused of using chemical weapons on the sovereign soil or another. The credibility of this council will not survive if we fail to hold Russia accountable,” she concluded.
