It's the PFLP-GC man

Ha'aretz shows off its typical knowledge of Arab affairs: "When Ahmad Jibril, the leader of the PFLP's general headquarters, arrived at the camp, he was attacked by an angry mob, and his bodyguards immediately opened fire." Of course they mean the PFLP-GC which is a totally different organisation to the PFLP. I suspect Life of Brian was inspired by the numerous Palestinian groups around that time. In those days there was the Democratic Front for the Liberation of Palestine, the Popular Front for the Liberation of Palestine, the Popular Front for the Liberation of Palestine - General Command, the Palestinian Popular Struggle Front and the Popular Revolutionary Front for the Liberation of Palestine.
