Available operational information shows that the supply of radiochemical substances to the territory of Ukraine for further disposal continues, which turns the country into a dumping ground for spent nuclear fuel and wastes of hazardous chemical industries, Kirilov told reporters.

The senior official added that the main supply routes for the substances are established through the territory of Poland and Romania. These substances ‘can be used to create a so-called dirty bomb’ and then use it ‘under a false flag’, he added.

Kirilov also said that, in the course of the special military operation, Moscow has obtained documents from the Security Service of Ukraine (SBU) confirming that Kiev is interested in ‘continuing to work with weapons of mass destruction’.

In this context, he added that the SBU requested the Ukrainian Academy of Sciences to allow the entity investigate samples of chemical, radiological, nuclear weapons, and traces of their use.

On June 20, Russian President Vladimir Putin said that Moscow is considering changing its nuclear doctrine due to the development of ultra-low-yield nuclear explosive devices and proposals to lower the threshold for the use of nuclear weapons.

At the same time, Putin specified that Moscow does not contemplate launching a preemptive nuclear strike, since a retaliatory strike guarantees reciprocal destruction.
