The Syrian Arab Republic has been a victim of terrorism. Since the start of the Syrian Civil War, Syria has been swept by multiple terrorist acts, initiated by radical anti-government Islamist groups, chiefly by the Islamic State in Iraq and Syria and in some cases Jabhat al-Nusra (al-Nusra).
From 1976 to 1982, Sunni Islamists fought the secular Ba'ath Party-controlled government of Syria in what has been called "long campaign of terror". Islamists attacked both civilians and off-duty military personnel.
The Muslim Brotherhood was blamed for the terror by the government, although the insurgents used names such as Kata'ib Muhammad (Phalanges of Muhammad, begun in Hama in 1965 Marwan Hadid) to refer to their organization.
Following Syrian occupation of Lebanon in 1976 a number of prominent Syrian officers and government servants, as well as "professional men, doctors, teachers," were assassinated. Most of the victims were Alawis, "which suggested that the assassins had targeted the community" but "no one could be sure who was behind" the killings.
Among the better known victims were:
These assassinations led up to the 16 June 1979 slaughter of cadets at the Aleppo Artillery School. On that day a member of school staff, Captain Ibrahim Yusuf, assembled the cadets in the dining-hall and then let in the gunmen who opened fire on the cadets. According to the official report 32 young men were killed. Unofficial sources say the "death toll was as high as 83." This attack was the work of Tali'a muqatila, or Fighting Vanguard, a Sunni Islamist guerrilla group and spinoff of the Muslim Brotherhood. `Adnan `Uqla, who later became the group's leader, helped plan the massacre.
The cadet massacre "marked the start of full-scale urban warfare" against Alawis, cadre of the ruling Ba'ath party, party offices, "police posts, military vehicles, barracks, factories and any other target the guerrillas could attack." In the city of Aleppo between 1979 and 1981 terrorists killed over 300 people, mainly Ba'athists and Alawis, but also a dozen Islamic clergy who had denounced the murders. Of these the most prominent was Shaykh Muhammad al-Shami, who was slain in his own mosque, the Sulaymaniya, on 2 February 1980.
