Siklawi, Rami. “The Palestinian Refugee Camps in Lebanon Post 1990: Dilemmas of Survival and Return to Palestine.” Arab Studies Quarterly 41, no. 1 (2019): 78–94. https://doi.org/10.13169/arabstudquar.41.1.0078. "It is important to note that before 1976 there had been 15 official Palestinian refugee camps in Lebanon (recognized by the UNRWA); however, Nabatiyeh refugee camp was completely destroyed and wiped out by Israel in 1974; Tal al-Zatar and Nab'a Palestinian refugee camps were both located in East Beirut, they were completely destroyed by the right-wing militias in 1976"
Time magazine, Middle East: Bullets, Bombs and a Sign of Hope, 27 May 1974. "The air assaults were far more devastating than the Lebanese or the Palestinians could have expected. This time the Israelis hit not just fedayeen strong posts but also camps occupied by civilian refugees. [...] The heaviest casualties were at Nabatieh, another refugee camp populated by about 5,000 Palestinians. The Israelis hit there in waves; two hours after the initial attack, more jets swooped down even as rescue workers were still clawing through the rubble for survivors. In the multiple strikes a total of 30 people were killed and at least 100 wounded. The camp was so badly damaged that bulldozers were brought in to level it."
