The UK's ambassador to the UN has condemned Russia's claims to have discovered evidence of biological weapons in Ukraine as "a grotesque lie".
Dame Barbara Woodward said Moscow is "sinking to new depths" with the claim and accused it of committing war crimes in Ukraine.
"We do not sit in this chamber to be an audience for Russia's domestic propaganda, and we should not allow Russia to use its permeant seat to spread disinformation and lies," Woodward said
"Russia has broken its commitments under the charter, but we must not let it subvert the multilateral system itself", she went on.
"As the UN said today, Russia is not putting at threat the global framework for peace and security."
