This was stated by a representative of the Defence Intelligence of Ukraine on the air of a national telethon
“The kremlinʼs statements about Ukraineʼs intention to allegedly use a "dirty bomb" are not only a psychological, but also a geopolitical operation, aimed at the outside world with the aim of forcing the Ukrainians to accept the fact of occupation and conduct negotiations with the aggressor.
The whole world did not believe in this outright fake, it is an absolutely failed informational and psychological operation. On October 24, a closed meeting with representatives of diplomatic and other missions took place in Moscow, where the special services tried to scare international representatives with a terrible threat from Ukraine - a 'dirty bomb'. Of course, no one believed. Because it's all was made up, and there is no evidence. In addition, the whole world sees in reality who is the aggressor, who attacked, and who is engaged in terror against the civilian population,” Yusov emphasized.
