In Zahedan Central Prison, southwest of Iran, inmates must pay nearly $30 if they seek being transferred to another ward.

Prison authorities have already reduced daily rations of bread, aiming to extort the prisoners. They are forced to pay $1 for each loaf of bread, and those who cannot afford it go days in hunger.

“We have to send money for our loved ones in prison so they can purchase food from the prison shop,” according to one of the prisoners’ families who wished to remain anonymous.

Many of the inmates are starving because their families cannot send them money, the source added.
