From Le Monde an account by a French doctor on the scene (translated by a reader):
Benghazi was attacked on Thursday. Our ambulances on the ground counted 75 deaths the first day; 200 on the second; then more than 500. From the third day, I had no more morphine or medications. In the beginning, the forces of repression fired on people in the legs and abdomen, then in the thorax and head. Then we saw mortar shots and rounds of anti-aircraft fire, directly into the crowd. A carnage. People were burned to death, shredded into bits. Altogether, I think there were more than 2000 killed; two hospitals of more than 1500 beds each were filled to capacity.
