Taking the world stage for the last time as secretary-general, Ban Ki-moon unleashed years of pent-up anger at leaders who keep "feeding the war machine" in Syria, violate human rights and prevent aid deliveries to starving people.
The U.N. chief told leaders at Tuesday's opening of General Assembly's annual ministerial meeting that "powerful patrons" of both sides in the more than five-year Syrian conflict "have blood on their hands."
"Present in this hall today are representatives of governments that have ignored, facilitated, funded, participated in or even planned and carried out atrocities inflicted by all sides of the Syria conflict against Syrian civilians," he said.
