Donia Al-Watan (independent Palestinian news agency) - Feb. 20, 2017

 
     “Fatah Movement Supreme Leadership [Council in Gaza] member Yahya Rabah emphasized… in a special interview with [independent Palestinian news agency] Donia Al-Watan that the PA has gotten over the subject of [exiled Fatah leader Muhammad] Dahlan and considers it a thing of the past…
Regarding the appointment of Mahmoud Al-Aloul as Fatah Movement Deputy President (sic., Deputy Chairman), Rabah noted that this is a good choice, and [PA President Mahmoud] Abbas is interested in a man who will help him and not hinder him, and Al-Aloul has a great history within the movement, and he has respected standpoints as he was one of the aides of deceased Martyr (Shahid) Khalil Al-Wazir ‘Abu Jihad’ (i.e., former head of the PLO terror organization’s military wing), and added that he commands great respect from the Palestinian people and Fatah people and members.”

Abu Jihad (Khalil Al-Wazir) was a founder of Fatah and deputy to Yasser Arafat. He headed the PLO terror organization's military wing and also planned many deadly Fatah terror attacks in the 1960’s - 1980’s. These attacks, which killed a total of 125 Israelis, included the most lethal in Israeli history - the hijacking of a bus and killing of 37 civilians, 12 of them children.
