"Our well-founded questions to the US and Ukraine have yet to receive a proper response. They remain open and need to be addressed," Vorontsov stressed during a meeting of the UN General Assembly First Committee.
Vorontsov pointed out that Russia has provided a "mass of evidence" regarding the US military biological program and emphasized that the facts regarding its implementation in Ukraine with the support of the Defense Department and affiliated entities requires close attention.
"The projects carried out in Ukrainian laboratories lead to the conclusion that biological weapons components were being developed in close proximity to Russian territory," Vorontsov emphasized.
Since March 2022, Russia has repeatedly accused the United States of conducting in Ukraine biological research for military purposes. Russia has pointed out that up to 30 biological laboratories in Ukraine were likely involved in biological weapons production. The United States has denied the allegation.
