A UN report on the Millennium Goals of eradicating poverty and hunger by 2015 has found that millions in sub-Saharan Africa are sinking deeper into poverty.
Millions in Africa still face poverty, war and disease
The UN adopted eight targets in 2000, which also included the reduction of child mortality.
The study finds 11 million children under five are dying every year, many of them from preventable or treatable diseases such as malaria and measles.
The report will put more pressure on G8 leaders ahead of next month's summit.
UK Prime Minister Tony Blair has already said he wants a landmark deal for Africa secured at that meeting.
On current trends, the UN will miss the targets it has set on hunger, infant mortality and education, its development agency says.
In a progress report on the Millennium Development Goals, the UNDP says global poverty rates are falling, but millions of the poor in sub-Saharan Africa are only getting poorer.
More than 800 million people worldwide do not have enough to eat, while more than a quarter of children under the age of five in developing countries are malnourished.
The UN finds that if the Millennium target of reducing the under-five death rate by two-thirds is to be met, there will need to be a drastic reduction in child mortality in Africa and southern Asia.
