“17-3. ICRC Visitation Rules
The following rules apply to ICRC personnel while
they are at any part of Camp Delta.
a. ICRC personnel are allowed to talk to detainees on all blocks at the detainee’s cell as long as there is no interference with the safeguard of U.S. Forces or detainees, except for detainees placed at the Maximum Security Units (MSU).
b. ICRC personnel are allowed to talk to detainees who are placed in MSU for disciplinary reasons only with the exception of the following:
(1) Detainees placed in MSU by the JIG will be listed on the MSU log. Their level of allowable contact
with ICRC will be listed on the MSU log.
(2) If the log is unavailable, the PL or SOG will contact the JIG during duty hours for clearance. They will also receive from the JIG what visitation level the ICRC has with the detainee.
(3) Detainees will not be allowed to leave the MSU block for ICRC visits
17-4. Levels of Visitation
All detainees will have a level of ICRC contact designated for them. These different levels are as follows:
a. No Access: No contact of any kind with the ICRC. This includes the delivery of ICRC mail.
b. Restricted: ICRC is allowed to ask the detainee about health and welfare only. No prolonged questions.
c. Unrestricted: ICRC is allowed full access to talk to the detainee.
d. Visual: Access is restricted to visual inspection of the detainee’s physical condition. No form of communication is permitted. No delivery of ICRC mail.”
The US has always denied it did not allow the International Committee of the Red Cross (ICRC) to visit detainees.
