With the Israeli invasion of Lebanon in 1982 the group lost much of its organization and support. Previously sympathetic Palestinian organizations, including the Palestine Liberation Organization (PLO), withdrew their support and passed materials to the French intelligence services in 1983, detailing ASALA operatives. One of the group's last attacks, on 19 December 1991, targeted the bullet-proof limousine carrying the Turkish Ambassador to Budapest. The ambassador was not injured in the attack, which was claimed by ASALA in Paris.
