Hajj Ismail Jaber
He was previously the head of the National Security Forces (NSF) in the West Bank from 1994 to 2005. He resigned due to rising intra-Fatah violence in the West Bank. Jaber then served as deputy head of the General Intelligence Service (GIS) – under Tawfiq Tirawi. In 2009, he was appointed by Mahmoud Abbas as a senior adviser on military and governorate affairs. He stood as a candidate for deputy-chairman of the Fatah CC in 2017 against Mahmoud Aloul.
According to a WINEP profile, Jaber “joined Fatah in Syria after 1967, traveling to China for training and then returning to Jordan to help establish guerrilla bases. Jabr was subsequently a senior PLA officer in southern Lebanon in the 1970s and early 1980s—rising to command all forces in the region—and in Iraq between 1984 and 1994.”
