(Photograph) - Give girls a chance: As 175 world leaders gather in New York this week to review progress on the United Nations Millennium Development Goals, anti-poverty group ActionAid says one of the key aims - primary education for all girls - has been missed in 70 countries. The target was set for the end of 2005 but the charity says two in three of the 100 million children who have never been to school are girls. Educated girls are more likely to have their own children immunised, and less likely to contract sexually transmitted diseases. ActionAid said reference to this failure had been omitted from a speech due to be made at the summit, and leaked to the charity. The Millennium Development Goals were made by the UN in 2000.
