A resistance fighter from Ukaine's Azov Battalion has made claims, which cannot yet be verified, that chemical weapons were used by Russian forces in the besieged port of Mariupol.

Speaking to ITV News, Illia Samoilenko said: "The enemy dropped the canisters with some kind of aerosol chemical. It was like a cloud of fog or something, like a cloud of smoke." Report by Buseld. Like us on Facebook at http://www.facebook.com/itn and follow us on Twitter at http://twitter.com/itn
