US calls for transparency as Russia investigates plague researcher death

US Secretary of State Marco Rubio has urged Russia to provide greater transparency regarding the death of a scientist at a Siberia-based plague research centre, according to diplomatic sources. The laboratory worker's death has raised concerns among international health authorities about potential disease transmission and biosafety protocols at the facility.

Official reports indicate that multiple individuals who had contact with the deceased researcher have been placed in quarantine as a precautionary measure. Russian health officials have initiated an investigation into the circumstances surrounding the death, though details remain limited.

The incident has drawn attention to Russia's biosafety practices and the handling of highly infectious pathogens at its research institutions. International health bodies have expressed interest in obtaining more comprehensive information about the case and the facility's operational procedures.

Russia's State Research Center of Virology, which operates plague research programmes, has not yet released detailed statements about the incident. Health authorities in neighbouring regions have reportedly been notified and are monitoring the situation closely for any signs of disease transmission.
