US, Ukrainian officials brace for possible Russian chemical attack

Top U.S. and Ukrainian officials are bracing for Russia’s potential use of chemical weapons in the ongoing conflict between Moscow and Kyiv, although the Pentagon on Sunday said the U.S. has not seen signs of an “imminent chemical or biological attack right now” on Ukraine.

Questions over a possible chemical weapons attack by Russia emerged this week after Moscow accused the U.S. of housing biological weapons in Ukrainian territory — a statement the White House rejected.

The U.S. has warned that Russia may be making such claims to lay false pretexts for a potential attack by Moscow.
