On Thursday, the Netherlands said they prevented a Russian spy from infiltrating the International Criminal Court (ICC).
The ICC is investigating war crimes in Ukraine.
The Russian spy traveled to the Netherlands in April, under the fake identity as 33-year-old Brazilian citizen named Viktor Muller Ferreira
The man was later identified as 36-year-old Sergey Vladimirovich Cherkasov, an agent of Moscow's GRU military intelligence.
He was due to start a six-month trial period at the ICC as a junior analyst in the Preliminary Examinations Section.
Brazilian federal police detained the man after he was turned away from the Netherlands for using a fake ID.
The GRU has spent 12 years creating this fake identity.
