“We will consider the use of the “dirty bomb” by the Kyiv regime as an act of nuclear terrorism,” TASS quotes the text of the letter.

Earlier, Dmitry Polyansky, First Deputy Permanent Representative of Russia to the UN, said that the Russian side would send a letter to the Secretary General of the United Nations António Guterres against the background of information that appeared about the risk of using a “dirty bomb” by Kyiv.

The UN, commenting on the data on the preparation of a provocation by Kyiv, called on all parties to avoid actions that could lead to escalation and miscalculations.
