The Millennium Development Goals can still be met if enough work is done, the UN secretary general has said.
Ban Ki-moon told world leaders, meeting in New York to review the targets, that they had already achieved much to be proud of.
But he said "the clock is ticking, we have much more to do" if the goals are to be met by the 2015 deadline.
The eight goals set 10 years ago aim to reduce poverty and hunger and improve health standards around the world.
