Among the tragic aspects of the War in Lebanon (1982) was the September 1982 massacre by Christian Phalangist forces of Palestinians at the Sabra and Shatila refugee camps in the Beirut area. The resultant anguish within Israel over possible Israeli involvement led to the decision to create a commission of inquiry, headed by supreme court chief justice Yitzhak Kahan.
