UN Secretary General Kofi Annan also spoke Tuesday in what was billed as his final address to world leaders before he steps down at the end of the year. Annan spoke about the need to end the crisis in Darfur.

• UN Secretary General Kofi Annan: “Sadly, once again the biggest challenge comes from Africa–from Darfur, where the continued spectacle of men, women and children driven from their homes by murder, rape and the burning of their villages makes a mockery of our claim, as an international community, to shield people from the worst abuses.”
