Russia has released American citizen Robert Gilman, who had been detained for over four years on assault charges. Russian President Vladimir Putin granted Gilman clemency citing health concerns, according to U.S. officials. Gilman, a former Marine, was accused of attacking a police officer, leading to his imprisonment. Advocacy groups had previously reported that Gilman suffered both physical and psychological torture while incarcerated. They warned his health was rapidly deteriorating and he faced a life-threatening situation. His release follows ongoing efforts by organizations working for the freedom of American detainees in Russia. The circumstances surrounding his initial arrest and subsequent treatment remain a point of contention.
