As the conflict raged, other Arab governments attempted to negotiate a peaceful resolution. As part of this effort, Gamal Abdel Nasser led the first emergency Arab League summit in Cairo on 21 September. Arafat's speech drew sympathy from attending Arab leaders. Other heads of state took sides against Hussein, among them Muammar Gaddafi, who mocked him and his schizophrenic father King Talal. A ceasefire was agreed upon between the two sides, but Nasser died of a massive heart attack hours after the summit, and the conflict resumed shortly afterward.
