MOSCOW — Russia’s penitentiary system has come under scrutiny after a Kremlin critic said he was tortured at a prison camp and forced to shout, “Putin is our president!”Ildar Dadin, 34, made the claims in letters that his attorney and his wife in November smuggled out of the prison camp in Karelia, a remote region in northwestern Russia. He also said he was severely beaten on numerous occasions, hung up by his cuffed hands and threatened with rape. He said the head of the prison camp, a Maj. Sergey Kossiev, personally oversaw the torture sessions.
