Analysis of information sources in references of the Wikipedia article "Black September" in English language version.
The composition of these two groups right up to September 1970 did not reflect a Jordanian-Palestinian divide. For instance, Nayef Hawatmeh, the head of the Democratic Front for the Liberation of Palestine (DFLP), one of the most radical Palestinian organizations, comes from Salt in the East Bank. On the other hand, General Mohammad Rasoul Al-Keilani, who headed Jordan's General Intelligence Directorate, came from a family that originates in Nablus in the West Bank. The point here is that the fighting of 1970 and the events that followed was the cause of a Jordanian-Palestinian divide, and not the result of one.
