Foreign Secretary Liz Truss vowed to hold Vladimir Putin “and his regime to account” if it is proven Russian forces used chemical agents in an attack on Mariupol. She tweeted last night: “Reports that Russian forces may have used chemical agents in an attack on the people of Mariupol. We are working urgently with partners to verify details.
“Any use of such weapons would be a callous escalation in this conflict and we will hold Putin and his regime to account.”
Meanwhile, Ukrainian President Volodymyr Zelensky called for a "mandatory" oil embargo against Russia to force the invading nation to halt its warnings over potential use of chemical weapons. He said upcoming sanctions being discussed by the EU must be strong enough "that even a word about weapons of mass destruction is no longer heard from the Russian side"
