This AP headline sent out on the wires reads:
3 Fatah Activists Killed in Israeli Raid
You have to read the article to find out:
The three men killed Saturday were identified as members of Fatah's violent Al Aqsa Martyrs' Brigades, a group that carried out many shootings during the second Palestinian uprising, which erupted in 2000. The deputy governor of Nablus, Anan Attireh, said one of the men — Anan Subeh — had been accepted in Israel's amnesty program for Fatah gunmen, while two others, Ghassan Abu Sharah and Raed Suragji, were still on Israel's wanted list.
Most Fatah gunmen are dead, in prison or retired, but those who remain active threatened revenge.
They're only "activists" in the sense that they were still actively attacking Israelis before the army caught up with them.
