UN chief vents frustration in last GA speech

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 UN chief told presidents, prime ministers, monarchs and ministers at the opening of General Assembly's annual ministerial meeting on Tuesday that "powerful patrons" on both sides in the more than five-year Syrian conflict "have blood on their hands".
