US monitoring death of Russian lab worker Darya Shipilova from suspected plague in Siberia
US Secretary of State Marco Rubio said the US is closely monitoring the case of Darya Shipilova, a Russian laboratory worker who died last week at a plague research institute in Irkutsk, Siberia. Russian authorities attributed the death to "pneumonia of unknown origin" and denied a lab accident, while hundreds have been placed in quarantine.
