Russia downplays plague fears after lab researcher's death

The World Health Organization and the US government are demanding more information from Russia regarding the death of a 28-year-old researcher at a Siberian anti-plague facility. While Russia claims the woman died from pneumonia of unknown origin and denies further infectious disease cases, the US has issued a formal diplomatic demarche. This request follows reports of quarantine procedures at the lab, as the Trump administration seeks clarity on the circumstances surrounding the researcher's passing.
