However, the relations among the participants became tense mainly due to Frangieh's pro-Syrian approach. In addition, in 1978, Suleiman Frangieh's son Tony and his family were killed by armed Kataeb militiamen trying to kidnap him acting on orders from Bashir Gemayel, the son of Pierre Gemayel. The incident is known as the Ehden massacre. It was this turning point that prompted Suleiman Frangieh to resign from the Front.
