In 1988, during the First Intifada, Ofer Prison and Ktzi'ot Prison were rebuilt, and Megiddo Prison stopped accepting Israeli military prisoners and changed its designation as a full-fledged incarceration facility for Palestinians. Smaller detention facilities were built in the bases near Dhahiriya, Tulkarem, etc. A special department in the corps headquarters was created to deal with Palestinian prisoners, and a special forces unit called Force 100 was founded to deal with rebellions in the prisons, and operated until 2006. A professional course for jailors who worked in these prisons was also created.
