The Kremlin on Thursday denied a U.S. accusation that Russian forces in Ukraine had violated an international ban on chemical weapons.

Kremlin spokesman Dmitry Peskov told reporters that Moscow remained bound by its obligations under the treaty that bans chemical weapons.

The United States on Wednesday accused Russia of violating it by deploying the choking agent chloropicrin against Ukrainian troops and using riot control agents "as a method of warfare" in Ukraine. (Reporting by Reuters; Editing by Mark Trevelyan)
