Moscow on March 27, 2018 charged Washington had put "colossal pressure" on allies to expel scores of Russian diplomats, and vowed to retaliate. The expulsions, made as a response to the poisoning of Russian double agent Sergei Skripal and his daughter Yulia with a nerve agent in the English city of Salisbury on March 4, were ordered by the United States Canada and Australia as well as a number of European Union countries, Albania and Ukraine. / AFP PHOTO / Yuri KADOBNOV (Photo credit should read YURI KADOBNOV/AFP via Getty Images)
