Poland's President Andrzej Duda said in an interview on Sunday that the use of chemical weapons in Ukraine by Russia would be a game-changer and NATO would have to think seriously about how to respond.
A "game-changer"
Asked if the use of chemical weapons by Russian President Vladimir Putin would be a red line for NATO at which point it has to get involved, Duda told BBC television: "If he uses any weapons of mass destruction then this will be a game-changer in the whole thing."
"For sure, the North Atlantic Alliance and its leaders led by the United States will have to sit at the table and they will really have to think seriously what to do because then it starts to be dangerous."
Since President Vladimir Putin launched the Russian invasion of Ukraine on Feb. 24, the United States has been concerned that the NATO alliance should not get dragged into a wider war with Russia.
Western officials said on Friday that Russia might use chemical weapons in Ukraine in a "false flag" attack to provide a retrospective justification for its invasion, but there was nothing to suggest a broader use of such weapons in the war.
