 About 30,000 Afghan refugee students from JUI-controlled madrassas (both JUI-F and JUI-S) in Pakistan joined the Taliban movement in Afghanistan.JUI party workers and leaders are mostly products of the madrassa system, although the JUI-F has often fielded candidates from a mainstream educational background.Both JUI factions have backed other India-oriented Deobandi militant groups, particularly the Harkat-ul-Mujahideen and its offshoot, the Jaish-e-Mohammad, with JUI madrassas providing recruits for them.
