Russia, Ukraine trade allegations of chemical weapons use at global watchdog

Russia and Ukraine have accused each other at the global chemical weapons watchdog in The Hague of using banned toxins on the battlefield, the organisation said on Tuesday.
The Organisation for the Prohibition of Chemical Weapons (OPCW) said that the accusations were “insufficiently substantiated” but added that “the situation remains volatile and extremely concerning regarding the possible re-emergence of use of toxic chemicals as weapons.”
Last week, the U.S. said Russia had violated the international chemical weapons ban overseen by the OPCW by deploying the choking agent chloropicrin against Ukrainian troops and using riot control agents “as a method of warfare” in Ukraine.
Russia denied the allegations.
