Ban Ki-moon: 'Clock ticking' on UN development goals

Ban Ki-moon has hailed progress on the Millennium Development Goals, but warned that "the clock is ticking" if they are to be met by the 2015 deadline.

The UN secretary general's comments came as he addressed world leaders meeting in New York for a summit to review the targets.

The eight goals, set 10 years ago, aim to reduce poverty and hunger and to improve health standards around the world.
