Russia releases former U.S. marine after four years in prison

A former United States military veteran, who had spent more than four years in Russian custody on charges that his supporters say were unfounded, was released on Tuesday. The veteran had been held in a Russian prison where his advocates allege he endured abusive treatment and harsh conditions that exacerbated his health problems.

Human rights activists and the group that has campaigned for his release warned that the veteran was gravely ill and at risk of dying while incarcerated. They cited medical reports indicating that his condition had deteriorated significantly during his imprisonment and that the lack of adequate care had put his life in danger.

The release comes after a prolonged campaign by the veteran’s supporters and international observers who called for a fair review of the charges and for improved prison conditions. The authorities have not yet issued a statement on the circumstances of his departure from custody.
