Eduard Basurin was quoted by the Interfax news agency as saying Tuesday that the separatist forces ``haven't used any chemical weapons in Mariupol.''
Basurin's assertion followed his statement Monday on Russian state TV that the separatists will use ``chemical troops'' against Ukrainian soldiers holed up at reinforced positions at a giant steel factory in Mariupol ``to smoke them out of there.''
A Ukrainian unit defending Mariupol claimed without providing evidence that a drone had dropped a poisonous substance on its positions. It indicated there were no serious injuries.
