However , the LF attack on the pro-Syrian Marada Brigade militia of the Frangieh Clan that summer , which culminated in the infamous Ehden massacre , provoked another round of fighting in June – July . President Elias Sarkis threatened to resign in protest over the Syrian bombardment of East Beirut , but later withdrew his resignation when the shelling stopped . More fighting erupted in the fall , again followed by a ceasefire . In October 1978 , the Foreign Ministers of Lebanon and those Arab League states contributing to the ADF – Syria , Saudi Arabia , Kuwait , Sudan , Qatar and the UAE – met at the town of Beiteddine , in the Chouf District south-east of Beirut . The outcome of the meeting was essentially a reaffirmation of the role of the ADF and a strong condemnation of those dealing with Israel . This meeting , and subsequent discussions between Syria and Saudi Arabia led to the lifting of the siege of Achrafieh by the Syrians and the withdrawal of all Syrian troops from East Beirut , being replaced by Saudi and Sudanese ADF troops , whom the Lebanese Front leaders viewed as more impartial and less hostile towards the Christians than the Syrian forces . The settlement was welcomed by the Lebanese Front parties and marked the end of the clashes
