A human rights organization reported the beating of political prisoners in the central Iranian city of Yazd in an apparent fight staged to punish them..

Karun Human Rights Organization said the attack happened in Yazd Central Prison June 19, during which a number of prisoners were injured.

“The prison's medical facilities were insufficient to treat the injured, and some of the prisoners were transferred to Yazd City Hospital,” added the report.

Among the injured, Mohammad Haydari, 35, from Ahvaz, is known to be a political prisoner but there is no information about his health so far.

The Arab political activist, who was sentenced to 15 years in prison on the charge of moharebeh (War against God), was stabbed in the chest.

One of the prisoners who witnessed the conflict told Karun that more than 20 Afghan prisoners were also injured.

According to this report, another Arab political prisoner named Jafar Beit Abdollah, 33, who was sentenced to 16 years in prison on the charge of moharebeh was also injured on his arm.

Karun added that most of the Afghan prisoners and some political prisoners have been transferred to solitary confinement.

Yazd Central Prison is home to about three thousand prisoners, among them over one thousand foreign nationals held in the worst conditions.

Eleven political prisoners in Yazd live in inappropriate conditions and have to endure discrimination and insults from officials and targeted conflicts inside the prison staged to harass them.
