Another American is in Russian custody, but this is perhaps the most bizarre case so far. 72-year old Stephen James Hubbard pled guilty on Monday in a Moscow court to charges of fighting against Russia in the context of the Ukraine war.

He agreed that he was a mercenary on behalf of Ukraine. “Yes, I agree with the indictment,” RIA quoted him as telling the court. Russian media alleges that he had been part of a Ukrainian territorial defense unit in the eastern Ukrainian city of Izyum since the war’s start. Hubbard is the oldest American said to have been captured by Russian forces, but his family has disputed Moscow’s account.
