Formerly, the Taliban funded itself though the revenue of poppy (ingredient in opium) and support from Pakistan's Inter-Services Intelligence (ISI)

Following the Taliban's ouster in late 2001, the group re-emerged as a non-state terrorist entity.  Since 2001, the Taliban has murdered NGO workers, Afghan civilians, government officials, and policemen, among others.

al-Aqsa Martyrs Brigades -- Ally (Suspected)

The origins of the Tanzim ("Organization" in Arabic) lie in the leadership group of al-Fatah that remained in the Occupied Territories while the mainstream branch of al-Fatah, led by Yasser Arafat, was based in Jordan, Lebanon and finally Tunisia. After the 1993 Oslo Accords brought the al-Fatah and PLO leadership back to the Occupied Territories, tension rose. The Tanzim held political and military sway on the ground but were not included in the Palestinian Authority (PA) leadership, which was dominated by the mainstream faction of al-Fatah. Marwan Barghouti emerged as the leader of this group that soon found itself in opposition to the "Tunisians" who excluded them from positions of leadership. Barghouti originally acted as a reformer, crusading against corruption in the PA and advocating peaceful negotiations with Israel.  <P><br />As he realized that the time and political climate were not ripe for reform in the territories, Barghouti and his group resorted to terrorism, with the Tanzim rising to public prominence during the beginning of the al-Aqsa intifadah in September 2000. The exact nature of the relationships between the Tanzim, the al-Fatah leadership and the al-Aqsa Martyrs Brigades (another group linked to al-Fatah) remains unclear. Al-Fatah's leadership has publicly renounced terrorist activity and claims that the Tanzim and the al-Aqsa Martyrs Brigades operate independently. Many terrorist attacks within Israel and the Occupied Territories, however, were still reported as being the work of al-Fatah in general.
