The US authorities do not want Ukrainian troops to use Western long-range missiles to attack the Kursk region because of the limited number of shells that the US side can supply to the AFU.
This was reported by the CNN television channel.
At the same time, the US government does not oppose the use of ATACMS missiles for attacks on Crimea.
Earlier, The Wall Street Journal reported that the USA fears retaliation by Russia for the AFU attack on Kursk Region.
