US Secretary of State Rubio Comments on Siberian Pneumonic Plague Death; 200 Under Observation

A technician at the Anti-Plague Institute in Irkutsk, Siberia, died of pneumonic plague, with nearly 200 people under observation. Moscow denies a laboratory accident and calls the situation stable, while US Secretary of State Rubio's cryptic 'We know what we know' suggests possible official opacity. The incident raises concerns about potential underreporting and the risk of an outbreak, though the actual spread remains unconfirmed.
