Officials also said Black, an infantry soldier, did not tell his unit he was going to Russia, and did not receive any authorisation to go there. They said he was essentially on leave, as he left Korea to redeploy back home to Fort Cavazos.
It’s unclear, however, if US service members are specifically prohibited from travelling to Russia, although the State Department strongly advises US citizens not to go.
The arrest comes less than a year after American soldier Travis King sprinted into North Korea across the heavily fortified border between the Koreas. North Korea later announced it would expel King, who was returned to the US. He was eventually charged with desertion.
Russia is known to be holding several Americans in its jails, including corporate security executive Paul Whelan and Wall Street Journal reporter Evan Gershkovich. The US government has designated both as wrongfully detained and has been trying to negotiate for their release.
Others detained include Travis Leake, a musician who had been living in Russia for years and was arrested last year on drug-related charges; Marc Fogel, a teacher in Moscow who was sentenced to 14 years in prison, also on drug charges; and dual citizens Alsu Kurmasheva and Ksenia Khavana.
The soldier’s arrest in Russia was first reported by NBC News.
