Russian-backed forces deny using chemical weapons in Mariupol - Ifax

Russian-backed separatist forces did not use chemical weapons in their attempts to take full control of the city of Mariupol despite Ukrainian allegations to the contrary, Eduard Basurin, a separatist commander, told the Interfax news agency on Tuesday.

Ukraine's Deputy Defence Minister Hanna Malyar said earlier on Tuesday that Kyiv was checking unverified information that Russia may have used chemical weapons while besieging the southern Ukrainian port city.
