When Hafez al-Assad suffered from heart problems in late 1983, he established a six-member committee to run the country composed of Abdul Halim Khaddam, Abdullah al-Ahmar, Mustafa Tlass, Mustafa al-Shihabi, Abdul Rauf al-Kasm and Zuhair Masharqa. Rifaat was not included, and the council consisted entirely of close Sunni Muslim loyalists to Hafez, who were mostly lightweights in the military-security establishment. This caused unease in the Alawi-dominated officer corps, and several high-ranking officers began rallying around Rifaat, while others remained loyal to Hafez's instructions.
