Three Iranian prison officials were charged with premeditated murder in the deaths of three protesters Saturday. The Iranian military court announced indictments for a dozen officials from Tehran's Kahrizak Prison. Kahrizak officials initially said Mohsen Rouhol-Amini, Amir Javadifar, and Mohammad Kamrani, who had been protesting Iran's disputed June elections, died of meningitis, but a coroner found they had been beaten to death. The prison's sub-par conditions played a role in the men's deaths, the court found. About 4,000 people were arrested during the mass demonstrations earlier this year. Reports of prisoner mistreatment led Ayatollah Ali Khamenei to shut down Kahrizak two weeks before the men's deaths were reported.
