Russia has accused a dual Russian-German national and lawyer, German Moyzhes, of treason, the TASS news agency reported, citing law enforcement agencies. TASS said that Moyzhes had helped Russians obtain European residency permits. He is being held in pretrial detention in Moscow's Lefortovo prison after being transferred from a detention center in St. Petersburg, the agency said. TASS did not say when his trial would begin and Reuters could not immediately contact his lawyer. Moyzhes joins a growing list of foreign nationals and dual citizens detained in Russia who have found themselves caught up in a crisis in relations between Moscow and the West during the Ukraine conflict.
