“The United States and members of the international community have, of course, repeatedly warned about the potential for Russia to use chemical or biological weapons in Ukraine,” Psaki said.
In a statement issued by NATO last week, the alliance’s leaders said their continued support to Ukraine would include helping protect it against potential chemical, biological or nuclear attacks.
Earlier this month, a spokesman for the European Commission has said that Brussels has received indications that Russia may use chemical or biological weapons in Ukraine
Speaking to reporters on Monday, Peter Stano said, as cited by the biznesalert.pl website:
“If chemical weapons are used, it will be very bad. We have already received indications regarding a possible staging of an attack with either chemical or biological weapons by the Russian occupying forces in Ukraine."
According to Stano, the indications are based on the fact that Russian officials are spreading information about "the so-called bio-chemical laboratory and other nonsense, which is absolutely not true,” biznesalert.pl reported.
