1975
PFLP-GC withdrew its membership from the PLO executive committee and central council, but did not remove itself from the PNC.
1977
Stalemate in Middle East peace process and Yasser Arafat's advocacy of a more militant resistance led to the PFLP-GC temporarily reoccupying its executive committee seat and rejoining the PLO.

Arafat’s recognition of U.N. resolutions calling for the rejection of terrorism led Jibril to participate in an Iran-sponsored plan to create a new organization to replace the PLO.
1990
A schism within the PFLP-GC developed as the group's representative to the PLO’s Executive Committee, Talal Naji, advocated rejoining the PLO and opposing Arafat’s policies from within, as well as rejecting growing ties with Iran. The PFLP-GC compromised by continuing contacts with Tehran, yet allowing Naji to veto political decisions.

On the same day, three Katyusha rockets were launched from southern Lebanon at Nahariya, a city in northern Israel. The attack caused minor damage and injuries.
