US Defence Inspector General Robert Storch has said that more than 50 criminal cases have been opened after a review of US arms deliveries to Kiev, including those involving contractors.
The Bloomberg news agency reports that these cases are currently at different stages.
It is noted that so far the Pentagon has not confirmed any of the charges, although it is possible that in the future any of them will be brought to trial.
In September, it was reported that the Pentagon will conduct an audit after the overpricing of equipment sent to Kiev.
