On the evening of May 9, a former Ukrainian diplomat was harshly detained in central Budapest. He is suspected of espionage, informs Telex. According to the Hungarian government's Facebook page, the National Immigration Administration banned a Ukrainian citizen from entering or staying in the country due to suspicions of espionage.

Ukrainian security services claimed to have uncovered a Hungarian spy ring gathering information about military activities in Ukraine’s western Transcarpathia region.

Hungary's foreign ministry then responded to the allegations by expelling two Ukrainian diplomats, accusing them of engaging in Ukraine's own espionage activities. The incident marks the first time in Ukraine's history that a Hungarian espionage operation had been discovered,
