A coroner’s report says that a man arrested in the violent aftermath of Iran’s presidential elections died from beatings, Iranian media reported Monday in what appeared to be the first official confirmation of a detainee’s death from mistreatment. The death of Mohsen Rouhol-Amini was the result of “repeated blows and severe physical injuries” and other mistreatment at Tehran’s Kahrizak prison, the semiofficial Mehr news agency reported, citing an informed source.
