Amnesty International is urging Burmese authorities to release all political prisoners and to reform the county's justice system.
The London-based rights organization published a report Tuesday detailing the cases of hundreds of the more than 1,300 political prisoners in Burma.
The report says the prisoners, who include farmers, politicians, teachers and students, have been held solely for peacefully-held views and activities.
Amnesty says these "prisoners of conscience" have been held in bad prison conditions and a large number are in poor health.
In the report, the rights group listed a dozen recommendations for Burma's State Peace and Development Council, including consideration of amnesty for all political prisoners.
