Secretary of State Rex Tillerson says the nerve agent used to poison an ex-Russian Spy in Britain "clearly came from Russia." He added that the move will "certainly trigger a response." In a statement, Tillerson said he's unsure if the Kremlin new about the poisoning, but he alleges that the nerve agent used in the attack couldn't have come from any other nation. Tillerson said it was "almost beyond comprehension" that officials of any government would use the poison in a public location. British Prime Minister Theresa May says it's highly likely the Russians were behind the attack.
Russian officials are calling the allegations a "provocation" and "nonsense."
