A woman with U.S. and Russian citizenship was arrested in Russia’s Yekaterinburg on treason charges, allegedly for raising funds for Ukraine’s military, the Russian state-owned news agency TASS reported on Feb. 20, citing the Russian Federal Security Service (FSB).
It sounds like she was already there back when Russia invaded in 2022.
That being said, the Department of State did already have a Level 4 “Do Not Travel” warning on Russia then, and already warned people to leave Russia immediately.
