According to official Pentagon figures, 516 Panamanians were killed during the invasion; however, an internal U.S. Army memo estimated the number at 1,000.[35]
The UN estimated 500 deaths[36] whereas Americas Watch found that around 300 civilians died. President Guillermo Endara said that "less than 600 Panamanians" died during the entire invasion. Former Attorney General Ramsey Clark estimated 3,000 civilian deaths. Figures estimating thousands of civilian casualties were widely rejected in Panama. The Roman Catholic Church estimated that 673 Panamanians were killed in total. Physicians for Human Rights, said it had received "reliable reports of more than 100 civilian deaths" that were not included in the U.S. military estimate but also that there was no evidence of several thousand civilian deaths.[4]
Twenty-three U.S. service members were killed[37] and 325 were wounded. But in June 1990, the U.S. military announced that of the casualties, 2 dead and 19 wounded were victims of friendly fire.[38] The U.S. Southern Command, then based on Quarry Heights in Panama, estimated the number of Panamanian military dead at 205, lower than its original estimate of 314.
