The Organization added that the harassment detainees are being subjected to is "unprecedented".

A number of detainees held in Building 13 said that police broke into their cells yesterday and confiscated a number of books, papers and pens as well as clothes items.

The security forces and police use metal rods, batons, firearm butts, "square" wooden planks and policemen shoes in torturing the prisoners.

Jaw Central Prison consists of six buildings in addition to building 10 that was prepared to host the arrested foreigners who reside in the country as illegal, but later the building was transferred to a special place to torture the prisoners of political backgrounds.

Prisoners were beaten and tortured in a brutal way in this building. Groans were emitted from this building and yells were heard. Calls for help echoed and prisoners of nearby buildings were able to hear them.
