US Secretary of State Marco Rubio said today (Tuesday) that Russia must be transparent following reports of the death of a laboratory employee due to infection with the plague in Siberia, adding that Washington is monitoring the situation “very closely.”

Rubio said during a visit to Iceland: “I believe that it is Russia’s duty, of course, to share more information with the world,” calling on it to be “transparent,” on a day when Russia’s Public Health Agency denied reports that health measures had been taken in the Irkutsk region in Siberia, after the death of an employee at a plague control institute.

The World Health Organization said today (Tuesday) that the Russian authorities have identified all the people who had contact with an employee who worked in a laboratory at the Plague Research Institute in Siberia and who died of unknown causes. Christian Lindmeier, spokesman for the organization, said: “It was reported that all people who had contact with the patient have been identified, and are being monitored to ensure that they are not infected with the disease, and none of them have shown any symptoms of the disease so far.” He added that the Russian authorities, who have not yet officially responded to the organization's request for information, are currently investigating whether pneumonic plague was the cause of her death.

In a related context, Kremlin spokesman Dmitry Peskov said that Russia welcomes the offer of assistance made by US President Donald Trump following the death of a researcher at the Russian Plague Research Institute. Peskov added that the Federal Authority for Supervision of Consumer Rights Protection and Human Welfare (Rospotrebnadzor), which is responsible for overseeing public health in Russia, is dealing with the situation and will provide more information as soon as it becomes available.

Three Iranians appeared before the British judiciary, today (Tuesday), on charges of spying for Iran, and they are suspected of paving the way for an attack targeting at least one journalist working for an anti-Iranian regime channel residing in London. The three had visited addresses linked to a number of people, including two journalists working for the Iran International channel. The three defendants, Mustafa Sabhund (41 years old), Farhad Manesh (46 years old), and Shapur Nouri (57 years old), appeared before the Woolwich Criminal Court in London. They all pleaded not guilty to the charges against them.

Prosecutor Bill Emlyn Jones told the jury that the three men were accused of carrying out actions likely to assist a foreign intelligence service. He added that they carried out surveillance and reconnaissance operations between August 2024 and February 2025. The Public Prosecution stated that Sabhund was supposed to carry out any possible attack. The three defendants did not deny that they visited those addresses and took photos and videos, but Sabhund said that he acted under duress and out of fear. The trial is expected to last up to 6 weeks.

On Tuesday morning, French President Emmanuel Macron supervised the experimental “first launch” of an intercontinental missile from a submarine off the coast of the west of the country. The presidency said that Macron followed the launch from aboard a frigate belonging to the National Navy. The Ministry of the Armed Forces explained in a statement that the missile, which is the third version of the M51 sea-to-surface strategic ballistic missile, was “devoid of its nuclear charge” and fell “in the North Atlantic Ocean, hundreds of kilometers from any coast.” The test comes amid increasing tension in Europe, as Emmanuel Macron warned of a change in the nature of “Russian aggression and threats” directed against European countries.
