According to this CNN interview with Josh Paul, a now resigned, former director at US Department of State,
I was part of the human rights vetting process for arms going to Israel. A charity called Defense of Children International Palestine drew our attention at the state department to the sexual assault, a rape, of a 13 year old boy in an Israeli prison at Moskobiya in Jerusalem. We examined these allegations, we believed they were they were credible. We put them to the government of Israel. You know what happened the next day? The IDF went into the DCIP offices and removed all their computers and declared them a terrorist entity.
Did the IDF or Israel declare the Defense of Children International Palestine a terrorist entity, and if so what was the stated reason (if provided)? Is there any evidence this happened after they raised allegations about child-rape in detention centers?
